Migrating your data from on-premise to Cloud is one of the tasks, that comes under the Cloud AppsDBA, after cloning, patching, and backing up.

This post covers 10 things you must consider when Migrating an Oracle EBS(R12) Environment from On-Premise to Oracle Cloud (OCI).

• if you are beginners to Oracle Apps DBA & wanted to know about the Must for an AppsDBA, check our post on  15 Things an Apps DBAs Must Know.

EBS Move & Improve Checklist

These are some of the most important considerations based on my experience with managing & migrating EBS R12 Customer on Cloud.

Migration / Lift-n-shift is one of the most important topics and as an Oracle Cloud Apps DBA, must know the skill.

In this post, I’ll cover, 10 things you should know or consider before moving Oracle Application (EBS R12) to Oracle Cloud.

Note: Do Check Our Blog Post on Oracle Zero Downtime Migration

1. OCI Service Portfolio

The first recommendation I would suggest is knowing the OCI Service Portfolio. As on a day-to-day basis, there are a lot of new features coming and this may be going to simplify our designing and solutions. To keep yourself updated with all the latest changes and new features in oracle Cloud Subscribe here.

2.Architecture & Topology

The second recommendation I will suggest to know the Architecture & Topology of your current environment. Collect all the information which directly affects architecture – Nodes, Concurrent users, Batch jobs, etc. This will help in deciding what services are needed and approximation on the Cost as well can be calculated. Check what options are available for DB systems on OCI and know the difference between DB on Compute, Bare Metal and Exadata. Check more Oracle EBS (R12) On Cloud Deployment Architecture.

3. Deployment models

Third, you should know various Deployment models at Oracle Cloud. Along with Public, Private, Hybrid options, you should also consider the Single & Multi-Region Deployment. Depending on the security, governance, and sensitivity of the data, select the deployment model. Of course, here you to consider the other aspects as well as budget & duration (whether it is for the long or short term).

4. Operating System Compatibility

Fourth, would recommend the Operating System Compatibility. What are the supported OS at cloud and apart from that what is your current OS? Whether it is binary compatible or you need to select the Cross-Platform Migration path will be decided with the OS compatibility. As of now at OCI – Linux, Windows, and Solaris (recently introduced) are supported.

if you are using EBS Cloud Manager then the Linux platform will be used.

5. Licensing of Products

Fifth recommendation to go with the Licensing of Products. Oracle gives a lot of discounts and also reuse of On-premise License at Oracle Cloud. So before you move to the cloud check the Licensing criteria with your Oracle Sales Representative.

6. How we will Migrate data

Sixth, we need to consider, how we will Migrate data. What the Database Size? Options you can use to migrate the data securely. We have Different Connectivity Options, FastConnect, VPNConnect, Data Transfer services. Depending upon feasibility and requirement we need to plan and decide which one should be beneficial and cost-effective. Apart from that, we need to think on the line on how to minimize the downtime for the migration so as to give maximum availability to the instances.

7. EBS Cloud Manager

Seventh I would recommend understanding EBS Cloud Manager which is the tool available only on Oracle Cloud to manage EBS. This is one of the tools which makes Oracle Cloud best suitable for EBS. Oracle is continuously adding new features and making our life easier. Cloud Manager has the capability to manage multiple EBS instances centrally and also provide options to run DB on Exadata and RAC. To know Oracle EBS(R12) Cloud Manager.

8.Security of your EBS Instance

The eighth recommendation will be the Security of your EBS Instance running on the Cloud. Depending on your architecture if external access is needed then you need to implement DMZ. Apart from that Oracle provides TDE at the database level, encryption of data either at rest on Storage or in transition, and multiple copies of files stored at Object/Archive storage. Also, Bastion Host adds an extra layer of security by not allowing direct access to any Application and Database servers.

9. Integration

The ninth recommendation will be Integration, how you can integrate various other Oracle or 3^rd Party Software with Oracle cloud EBS. SOA Gateway, Workflow Notification mailer setup, On-premise Printer integration all these are common integrations. Apart from that now Oracle & Microsoft Partnership is in place and the most common integration required by the industry is Azure AD integration with EBS for SSO requirement.

10. The lifecycle of EBS and various tools

Tenth one, last but not the least how you can maintain the Lifecycle of EBS and the various tools you are using to maintain EBS. You need to regularly update these tools to new versions, take backups. Apart from that EBS running on OCI also needs Patching, CPU updates, and upgrades. So your existing knowledge is also utilized apart from learning new skills.
