I have a pool with 2 hosts and 12 VMs. The VMs are on an attached SR. Currently, the version of XenServer is 6.0.2 and I need to upgrade to 7.1 but I was wondering what's the best way to do that considering I'm not an expert. I have 2 choices:
- Use Rolling pool upgrade
- Install as new the version 7.1
For both, I need some advice, so if I use
Rolling pool upgrade is this method stable enough to do this operation from 6.0.2 to 7.1? anyone had experience with that?
Install as new the version 7.1, in this case, I would proceed in this way:
- shut down all VMs
- backup all VMs information with
xe pool-dump-database file-name=backupPool
- detach server number one from the original pool
- detach the SR from the original pool
- install from scratch XenServer 7.1 on server number one
- create a new pool with only server number one on it
- attach the SR to the new pool
- import the backup taken at point 2
- now if everything is ok, I should be able to start the VMs and start again from point 5 with the server number 2
what's the best and safest way to proceed?
Thanks a lot
