multiple Database no DAG to DAG Model

Hello everyone,

I have 25 Exchange DB spread across 4 Exchange CAS+MBX role servers. I am planning to move them to DAG model but want to know from community how did you distributed the User MBX with different sizes to DAG Database.

Current total size is around 8.2TB for 2505 Users. I am planning to have 4 server two DAG model with A/A configuration.
