This issue has been solved. See solution.

Hi All,

    Does anyone here experience upgrading SEP 11.x to SEP 12.1 RU2? Although I've read it in the new features of SEP 12.1 RU2, I want confirmation if it is trully effective without passing on the migration path in the previous versions, Please confirmed, so I can proceed upgrading without hesitation. Thanks. ^^,

the upgrade should have been SEPM 12.1 Ru1 them to Ru1 MP1.

Since Ru2 is available, you may try in UAT
