There wont be any issue is you do not upgrade sep client to 12.1

Sepm needs to be upgraded first and not the client

11.0.6 client would be legacy for 12.1 Sepm and can be easily managed by 12.1 sepm not vice versa

sepm 11.0.6 and clients 12.1 no good idea ....

Make sure to copy the db and certificates to another drive before upgrading the sepm

you may also like to copy the policies and add them once the sepm is upgraded to 12.1

Make sure replication is disconnected before upgrade . If replication configured both the sites "Only sepm" needs to be on the same version and reconnect the replication .

Necessary info such as GUP machines configured their host names or Ip address make a note of them .

there are many good videos and articles on this .

First you need to upgrade your Endpoint protection manager (SEPM)  from 11.0.6 ---> 12.1 and than you can upgrade SEP clients.

SEPM 12.1 can managed SEP client 11.0.6 however Symantec recommends you  to be on same version for manager and client.

we are going to upgrade client machines from RU6 MP2 (and several from MR4 MP2, RU5 and RU6 MP1) to 12.1 RU1.

As I read above this is supported, correct? We don't need to upgrade first to 12.1 and then to 12.1 RU1?

Also SEPM can be upgraded directly from RU6 MP2 to 12.1 RU1?
