Upgrade QDB to Version 8 and move to new CCDB


Hi, I am looking for some direction on documentation, advice, White
Papers, etc... for the following upgrade scenario.

I have 2 environments.
Version 7.x.x
- Server A (QDB, CCDB)
- Server B (QDB)
Version 8.x.x
- Server 1 (QDB, CCDB)
- Server 2 (QDB)
- Server 3 (QDB)
- Server 4 (QDB)

I would like to perform and in-place upgrade of QDBs on Servers A & B
and move the Control Center management from the CCDB on Server A to thew
CCDB on Server 1. Then retire the Server A CCDB.

I will need to also move Management Servers, Control Center Monitoring
policies, etc. I am thinking to upgrade the agents from 7 - 8 after the
main QDB upgrade and CCDB migration.

Any tips, Best Practice, gotcha, advice would be appreciated!

Matt

Re: Upgrade QDB to Version 8 and move to new CCDB


it depends on what you want to do with the "migrate" part of it.

Basically - the monitoring in the QDB's that are on Servers A and B will
be lost (the monitoring that is controlled by Control Center - ie any
policies that a CC policies). Those 2 QDBs will be removed from CC on
Server A and then added to CC on Server 1. You can do that after
upgrading them in situ on their current location. Or you can move them
over to the new environment whilst they are still AM7 (so long as they
are patched accordingly).

I guess the easiest way forward is to get the AM7 environment upgraded
to the same version as the AM8 environment. Then remove the 2 QDBs from
CC. This will force a stop of all policies that were configured from CC.
Any ad-hoc jobs will remain, as will any policies that had been defined
in the QDB (so you can either leave them as they are or remove/stop them
in preparation for the move to the new CC environment).

Then you add the QDBs to the new CC environment where they will start to
inherit the policies defined there - either automatically from any Rule
Based MGs and wildcard based MGs, or as you add QDB views to MGs.

The agents can be upgraded at a time that is best - upgrading the core
components does not force you to upgrade the agents at the same time.
You can do that later. Also, adding the QDBs to the new environment has
no effect on the MSs for those QDBs. Those would be upgraded as a part
of the QDB upgrades, but can remain the same servers throughout. So the
agents from those QDBs will see no changes in core...
