Endpoint Protection

we had plan to upgrade to MR6 MP1, currently we still at MR5 (had problem with clustering on client so we would like to upgrade SEPM as well). as i read documentation for MR6 MP1, upgrade path is only possible if i install MR6a first, that mean i had to deploy MR6a first then continue with MR6 MP1? is this still the only way? i really want to confirm this before making any changes.

thank you and sorry if this question sounds silly...

regards,

andreas.

Symantec Endpoint Protection RU6 MP1 (11.0.6100) provides fixes since the release of RU6 and RU6a. This maintenance patch cannot be installed over any versions of Symantec Endpoint Protection or Symantec Endpoint Protection Manager prior to RU6. It must be installed over RU6 or RU6a.

RU6MP1 is a Maintenance  patch and not a maintenance release, A MP can only be installed on the main build. You can install RU6 over RTM or MR3 or MR4MP2 but not RU6MP1. For that you need to have RU6

 It is not recommend to upgrade directly from RU5 or MR4  to RU6MP1

This migration path is not supported.

Possible effects after a direct upgrade to RU6MP1  from a lower version [except RU6]:
Schema Corruption.
Possible dll corruption.
Policies Corruption.
Network breakdown.
Challenges with uninstalling SEP.

So what you need  Upgrade the clients to RU6 and then upgrade  to RU6MP1.

thanks for your response.

i will upgrade SEPM to RU6a first then to RU6 MP1.
will do the same for SEP clients, but this will take quite some time here..
