Can DAG servers temporarily have different amounts of RAM
I have 4 Exchange 2010 virtual Citrix servers, 2 CAS and 2 DAG members. I would like to take them offline one at a time and double their RAM. No questions on the 2 front end CAS servers, I would just separately take them down one at a time. But can I do the same thing with the DAG servers? Plan A would be to move the active mailbox database copies to DAG server 2 and take DAG server 1 offline for the changes. But when DAG server 1 is restarted and the DAG sees the two nodes once again DAG server 2 will have twice the amount of memory - is that going to be a problem when pushing the active mailbox copies over to DAG server 1 to finish the RAM upgrades?
In other words, will problems arise (quorum, witness server, etc,) if this is the way it is done?
