Hi Raj,
I would suggest you to run the Configuration Analyzer tool (download here) for SAP Net weaver identity Management as a first step to identify any potential issues that may cause some problem during the migration. The tool gives a report something like this. If there are any issues related to migration, it will also be listed. The details of the issues can be found in the Issues.csv file.
Checked database:<database_name>
Detected 640 potential issues.
12 issues of type: Possible 7.2 pure mode issue
41 issues of type: Data inconsistency issue
554 issues of type: Configuration issue
15 issues of type: Performance issue
18 issues of type: Deprecated functionality
If there are any issues related to migration, fix them first and plan for migration.
With my knowledge, I suggest you to proceed the following way.
1. Remove the access to IDM UI. bring it down from SAP NW Administrator.
2. Stop all the dispatchers & event agents.
3. Take a backup of your IDM database (Take help from your database administrator)
4. Upgrade the Management Console. - Follow the steps in Migration guide.
5. Upgrade the Runtime Components. - Follow the steps in Migration guide.
6. Upgrade the Identity Center database. - Follow the steps in Migration guide.
This is where you have to be careful.
1. You have to first upgrade the database of IDM to the version 7.2
2. You have to migrate the data from 7.1 to 7.2 - User Data Migration tool for this, which again explained very clear in the migration guide.
There is a crucial step here. after uo upgrade the IDM database in step 1, followed by Data
Migration tool, you have to upgrade the database schema again by running mxmc-update.cmd.
7. Upgrade dispatcher and event agent services. - Follow the steps in Migration guide.
8. Delete the provisioning queue.
9. install the provisioning framework 7.2
10. Disable the provisioning framework 7.1
11. Convert the identity store data to user provisioning framework 7.2
12. upgrade the configurations.
13. Test the configurations.
The details process steps on how to are given in the same upgrade guide.
All the best !!
