Your Key Takeaway
First things first, let’s take a brief look at your key takeaway from this guide!
In this guide, we’ll explore the top business drivers for organizations to modernize OBIEE with Power BI, along with the various options available for the modernization.
Our goal is to help you choose the best path for modernizing OBIEE with Power BI that results in quick wins without expensive re-engineering.
Oracle Business Intelligence Enterprise Edition (OBIEE) and Oracle Analytics Cloud (OAC) are Oracle’s offerings for data visualization needs. OBIEE was one of the most preferred BI data visualization platforms for enterprises before the introduction of Self-service Analytics.
But with the introduction of Self-Service Analytics, OBIEE has lost its crown as the preferred platform for Business Intelligence. The modern visualization tools such as Power BI have outclassed OBIEE in the self-service analytics landscape.
Though Power BI has a clear edge over OBIEE in the self-service game, OBIEE still has the upper hand over Power BI in the data management landscape.
Many organizations using OBIEE are considering switching to a modern visualization tool like Power BI either to replace OBIEE completely or to complement the limitations of OBIEE.
In this guide, we’ll see the top business drivers for organizations to modernize OBIEE with Power BI, along with the various options available to replace or complement OBIEE with Power BI.
This guide will walk you through the top business drivers for modernizing OBIEE with Power BI and explore the different options of the modernization.
2 Key Reasons for Modernizing OBIEE
In this section we’ll discuss the four key business drivers for organizations to consider modernizing OBIEE with Power BI:
- 2.1. OBIEE’s Limitations in Self-Service Data Visualization
- 2.2. Business Users’ Hunger for Self-service
- 2.3. Deployment of Modern Viz. Tools in the Analytics Stack
- 2.4. ROI of OBIEE to Power BI Transition
We’ll now see each of these business drivers in detail.
2.1. OBIEE’s Limitations in Self-Service Data Visualization
Data visualization is the biggest challenge for OBIEE users. Creating visualizations demand a tonne of technical know-how, and require a longer turnaround time.
Though OBIEE is far better than Power BI in its ability to handle complex schemas, joins, and aggregations, the decision-makers use OBIEE only for Business Intelligence purposes and don’t get to experience the ease of data management it provides.
Further, OBIEE doesn’t provide true self-service capabilities, as the users need the help of IT teams to prepare the data for visualization.
One of the key reasons for modernizing OBIEE is its lack of self-service data visualization capabilities.
2.2. Business Users’ Hunger for Self-service
If you’re a business user relying on OBIEE to derive insights and make decisions, you’ve probably realized that your analytical wings are clipped in the data visualization part.
The process of gaining insights is restricted to tabular reports with basic filters, and a limited set of data visualizations. You’re also unable to perform ad-hoc analytics in OBIEE during unforeseen circumstances.
However, when it comes to your wants, you’re envisaging many visualizations that could potentially uncover critical patterns for deriving in-depth insights that result in a confident decision-making experience.
Therefore, as a business user, you want to replace OBIEE with a self-service data visualization tool like Power BI.
2.3. Deployment of Modern Viz. Tools in the Analytics Stack
When organizations using OBIEE focus on modernizing the technology stack, OBIEE is one of the platforms getting a green signal for replacement or to be complemented with a modern data visualization platform.
OBIEE is seen as a legacy business intelligence platform. Hence, modern visualization platforms like Power BI make their way into the organization’s software stack.
Further, if there is an enterprise-wide adoption to Microsoft Azure stack, Power BI is the preferred data visualization platform as it is inexpensive and offers simple connectivity options to many cloud and on-premise data sources.
2.4. ROI of OBIEE to Power BI Transition
Return on Investment (ROI) is another key driver for replacing or complementing OBIEE with Power BI.
The business users of organizations using OBIEE typically spend more time in creating visualizations and a longer waiting time for the data to be prepared by IT teams. This results in delayed and inaccurate decisions.
Further, it is hard to uncover critical data patterns with OBIEE visualizations, and hence the decisions are made with less confidence level.
Now that we have seen the primary business drivers for organizations to modernize OBIEE with Power BI, let’s see the different options to get the modernization done.
3 Options For Modernizing OBIEE With Power BI
When modernizing OBIEE with Power BI, the following three options are available for organizations:
- 3.1. Migration from OBIEE to Power BI
- 3.2. Manual export/import from OBIEE to Power BI through spreadsheets
- 3.3. Connecting Power BI to OBIEE
The first option is the only option for replacing OBIEE with Power BI, while the other two are for complementing OBIEE’s limitations with Power BI.
Let’s explore each option in detail below.
3.1. Migration From OBIEE To Power BI
Currently, there are no tools to automate the migration of OBIEE reports and subject areas to Power BI. The migration from OBIEE to Power BI is therefore a manual process and has its own complexities.
Though migration is preferred by many organizations since it eliminates duplicate BI/Analytics environments, there are many obstacles to reaping the benefits of the migration.
3.1.1. Steps involved in OBIEE to Power BI Migration
From a bird-eye view, the migration project involves 3 steps:
1. Recreating connectivity to data sources from Power BI – When migrating from OBIEE to Power BI, the primary step is to recreate the connectivity from Power BI to all the data sources involved.
With OBIEE, it is quite easy to handle numerous data sources in the RPD without much hassle. However, recreating the connectivity that was created with decades of efforts in OBIEE in Power BI is cumbersome and often cost-prohibitive.
2. Redeveloping joins and measures in Power BI – After establishing connectivity with the data sources, the IT teams will have to get involved in another duplicated effort – redeveloping the relationships and measures in Power BI.
In OBIEE, managing complex relationships is not difficult. However, that’s not the case with Power BI.
3. Replicating OBIEE Security Framework in Power BI – Replication of the security framework from OBIEE to Power BI is another essential step. Depending on the Power BI plan you’re using you may require additional configurations to replicate the security model.
Upon the successful execution of the above steps, you can redevelop the existing reports in OBIEE. It is also important to enable the users to visualize data in Power BI with a brief training session.
3.1.2. Is migration from Power BI to OBIEE feasible?
Based on the steps involved for the migration project, the feasibility of the migration heavily depends on the number of data sources, the connector costs (if any) for each data source, the complexity of the security framework, and the redevelopment efforts.
The best starting point is to list down the data sources and segregate them into the following buckets based on their connectivity to Power BI:
- Power BI’s inbuilt connectors
- Off-the-shelf connectors
- Unique data sources that require inhouse custom connectors
Further, the costs associated with each of the connectors (if any) also have to be taken into account for the migration project.
Start with a project risk assessment if you’re choosing to migrate from OBIEE to Power BI, due to high project cost and timeframe.
Additionally, if you choose to go with an uncertified connector, it is necessary to ensure the connector doesn’t land you into security issues.
Let’s now take a brief look at the potential challenges in the migration project.
3.1.3. Potential Challenges
The major challenge to deal with in the migration project is the time and cost constraints.
BI Migration projects are sinkholes when it comes to the total cost and the timeframe for the project. Often the projects overwhelm IT and business teams for several years, cost millions of dollars, and in the end, leave both the business users and IT teams in the dust with frustration and failure.
For migrating 1 Subject Area, the approximate cost is $250,000 and the turnaround time is about 6 months.
As a ballpark, it is estimated that migrating OBIEE subject areas to Power BI would cost $250,000 per subject area. Each subject area migration could take up to 6 months.
BI migration projects are complex beasts and the corporate IT landscape is littered with more failures than success. So if you’re looking for creating quick wins or dealing with a stringent IT budget, migration might not be the right choice.
Avoid the migration option if you’re looking to create quick wins, as OBIEE to Power BI migration is a long-term project.
If your organization can handle the costs and time frame involved, migration could be the right choice.
3.1.4. ROI of OBIEE to Power BI Migration
Let’s assume your OBIEE has 10 subject areas.
So the total estimated cost of the project is $2,500,000, at a turnaround time of 5 years.
In the best case, the organization can start reaping the benefits of the migration, at least 5 years from the start of the project.
Figure 1: Cost-benefit analysis of the migration project
As inferred from figure 1, the project risk is very high, as it involves years of effort and costs millions of dollars.
Even if an organization is ready to take this huge risk, the biggest drawback of the migration approach is the users will have to wait for years to visualize data in Power BI.
3.2. Manual Export/Import From OBIEE To Power BI Through Excel
If your organization is using the approach of exporting/importing data from OBIEE to Power BI through spreadsheets for ad-hoc analysis, you seriously need to consider other options as this approach is manual and is highly error-prone and inefficient.
Let’s take a quick look at the pros and cons of this approach.
- 3.2.1. Pros and Cons of Manual Export/Import
- 3.2.2. Cost-Benefit Analysis of Manual Export/Import
3.2.1. Pros and Cons of Manual Export/Import
The only advantage of this manual export/import approach is the ability it gives to analyze OBIEE data without any additional setup. Since there is no setup required, this is a low-risk approach.
But the cons of the approach are multifold. The manual process is cumbersome, error-prone, and expensive due to productivity loss.
Each user typically spends 4 to 5 hours per week in exporting/importing data manually from OBIEE to Power BI and blending that data with other sources. This accounts for an approximate productivity loss of $10,000/user/year.
The approximate time spent in manual import/export is 4 to 5 hours/week/user.
Further, the disadvantages include:
- Inability to visualize real-time data.
- Limitations in the number of rows available for analysis due to spreadsheet-based constraints.
- User frustration due to manual efforts.
3.2.2. Cost-Benefit Analysis of Manual Export/Import
Assuming 10 users need to analyze OBIEE data in your organization, the productivity loss is $100,000/year for the organization.
Figure 2: Cost-benefit analysis of a spreadsheet-based approach
As inferred from figure 2, the costs far outweigh the negligible benefits. Hence, avoiding the manual approach is good for your organization.
Avoid the manual export/import approach as it results in a huge productivity loss of $10,000/year/user.
3.3 Connecting Power BI to OBIEE: The Bimodal Approach

The 3 options available for integrating Power BI to OBIEE are:
- Oracle BI Server ODBC Driver
- BI Connector
- Web Data Connectors
Let’s take a quick look at the connectors available for integrating Power BI with OBIEE.
188.8.131.52 Oracle BI Server ODBC Driver
The Oracle BI Server is an ODBC driver provided by Oracle for setting up DSNs of OBIEE data. Let’s take a quick look at the pros and cons of the driver.
184.108.40.206.1 Pros and Cons of Oracle BI Server ODBC Driver
The pros of using Oracle BI Server ODBC driver are less – It enables direct connectivity to OBIEE data and helps uncover insights out of OBIEE data using Power BI visuals.
However, the cons are many. The users need complex technical knowledge or assistance to connect. This driver is not as reliable as its performance is poor and getting it to work consistently is difficult.
Ignore the Oracle BI Server ODBC Driver if you can’t expose the key fields in OBIEE RPD in business and presentation layers for each folder/table analyzed in Power BI.
The other major disadvantage is the need for re-engineering in OBIEE. The key fields must be exposed in OBIEE RPD in business and presentation layers for each folder/table that is to be analyzed in Power BI.
