We recommend that you upgrade or migrate your repository before you start the EM upgrade process. Since you are doing cross platform db migration make sure that once it’s done the old EM 10.2.0.5 is working fine with the repository on new platform. The EM upgrade using 2-system upgrade approach will take care of the OMS upgrade and migration from one platform to another.

Grid Control Repository: Steps for Cross Platform Migration of the 10g Grid Control Repository [ID 388090.1]
For repository migration across platform refer to: http://docs.oracle.com/cd/E24628_01/doc.121/e24473/repository.htm#BGBEBBHE
So cross platform "UPGRADE" is fine?
Can you please elaborate more on when you say "make sure that once it’s done the old EM 10.2.0.5 is working fine with the repository on new platform"?
Also is it OK if I upgrade the 10g repository to 11gR2 in upgrade process?

Yes cross platform upgrade is fine. Once you have done the db upgrade make sure that data is up and running, you can login into the database.. etc to verify that DB upgrade was successfully.
Yes you can do this. Let me share some customer stories with you:
