Exchange 2010 - Modify DAG


I have a DAG-enabled mailbox database that is currently hosted on two servers:

Host1 - passive copy
Host2 - active copy

Now I need to:

- remove passive copy
- change active copy from Host2 to Host1

Do I first change the activationpreference then delete the passivecopy or the other way round ?

Mount on Host2 and remove the passive database (Host1) will automatically change the preference.

Once you remove passive copy. Exchange will automatically change it for you.
Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

I have a database that only has a single active copy, and I need to delete it. How do I do that via GUI ? the EMC doesn't have the remove button in database management / database copies......

thanks very much.

Upss. Sorry The remove button is the in database management section!

Just one more question. Once I delete it, will the database files still be available, in case we need to remount it ?

Thanks again for your help.

Yes, files will be present, until you remove them from the folder. Remount, I would not recommend, better to recreate fresh passive copy, as Exchange db update every second and old passive won't match.
