In reply to Paul Cunningham. Hi Paul, May I ask is it possible that this script for redistribution of databases can cause unhealthy DB copies or any problems with databases?

Would adding a flange to the crevice aid the flux capacitance too?

As John Mohler said, is it possible to move all db copies depending on the activation preference? For example, i have 3 servers, s1, s2 and s3. s1 and s2 are in one site, and s3 in other site. all copies os server 3 have AP 3. I would like to move all db to server3 by activation preference.

Thank you in advance.

Quick question… We see latency issues on DB’s and sometime, just moving the DB to a new server and back fixes the problem. Can this script move all db copies to ActivationPreference 2? Would you use the -activationpreference 2 switch?

Hi Paul

Thanks this is very helpful.
But I would like to go even a step further.
Not only divide the load of your databases but also divide the user load across the different databases.

The thing I would like to achieve is to get an even load (mailbox size wise) across all databases.
So not based on how many users there are on a database but based on mailbox sizes so that you get databases with almost identical sizes.

What are your thoughts on this?
Is it useful and possible to script this?

Thanks in advance.
