There is no stated best practice in terms of how to organize your baselines… I personally prefer making monthly patch baselines and deploying those and occasionally creating a yearly baseline to pick up the major updates.
Yes, when we upgraded to version 7 we installed a new server, so Marjan showed us this Mime setting. It is turned on and working good.
When you say monthly patch baselines, that sounds good, i usally have one Baseline per year, and monthly actions, and then i add the new fixlets every second month to the baseline, this is what i found easiest.
But then i shouldnt be afraid of having big Baselines like 100 fixlets. and having several Baselines.
