When you run the Upgrade program for the identity applications, ensure that you incorporate the following considerations:
Use the same database that you used for the previous User Application. That is, the installation from which you are migrating. In the installation program, specify Existing Database for the database type.
You can specify a different name for the User Application context.
Specify an installation location that is different from the one for the previous installation.
Point to a supported version of Tomcat.
Do not use case-sensitive collation for your database. Case-sensitive collation is not supported. The case-insensitive collation might cause duplicate key errors during migration. If a duplicate key error is encountered, check the collation and correct it, then re-install the identity applications. The only supported collation is SQL_Latin1_General_CP1_CI_AS.
