I have an existing cluster with sub and pub. Currently, they are at OS version 2000 4.2rs12.
I am adding another sub, with new hardware platform. The platform configuration cd's are for 2000 4.4. I understand that there may be some issues with this version, so it is advisable to upgrade to 2000 4.4a.
I will need to upgrade the existing pub and sub to 2000 4.4a. SO my question is, can I do a simple upgrade on the new box from 2000 4.4 to 4.4a? I will upgrade pub first, sub second, then introduce new sub into cluster at same ver.
