You cannot downgrade from Exchange 2010 Enterprise to Standard.  The only way to achieve this is to uninstall Exchange and reinstall using the correct product key.

However.....

You can have a mix of standard and enterprise servers in the same organization I believe (Never tested).
So in theory you can create a new exchange 2010 STD server in the same org. Migrate all your mailboxes and if you use them, public folders, and once you are happy that everything is moved over to the new STD server you can uninstall the ENT server. I would test in a lab first if possible.

AND BACKUP FIRST :D

I was refereing to #36548865

Your easiest way is to just ADD a server, move mailboxes and then remove your currecnt server. Nothing lost or recreated at all.

Hi Neil

Just to update the server is performing the role as CAS/HUB , so there is no need to move mailbox.

I don't have spare hardware to migrate is possible also

Wel you DO have spare hardware IF the server does not have Database on it!! You install ca/hub on the server that holds the databases, now ALL roles on there. Now you can remove exchange from server that had CAS/HUB on and do as I said....
