Trying to upgrade our ePO server from 4.5 Patch 4 to 4.6 Patch 7 and I'm getting a consistent failure each time shortly after trying to start new services. I can recover from it using the following method:
Backup ePO 4.5 as per McAfee Backup/Recovery article KB66616
Run 4.6.7 setup.exe
ePO 4.5 now in an unuseable state
Remove ePO 4.5 manually using KB66586
Re-install 4.5 Patch 4
Restore ePO 4.5.4 using KB66616
Re-run 4.6.7 setup.exe
Install completes with no problems.
Any ideas why I'm having this consistent failure on first attempt? There's nothing in the install logs that points to anything specific.
It's an absolute pain to have to upgrade using this method and it's not going to swing with management if that's the way we have to do it!!
