Our Exchange 2003 -Mailbox server running on low disk on the disk that holds the mail database.
Current database status:
Exchange version : Exchange 2003 6.5.7638.1- Enterprise Edition
Storage group Size
First Storage Group 347 GB( Two mailbox stores )
Second Storage Group 248 GB (Two mailbox stores )
F: Drive - Exchange Database - Free Space 103 GB
E: Drive -Exchange Log - Free Space 390 GB
We archived mails from lot of mailboxes and its giving white space only.We want to reduce the database size for easy handling and smooth function of the user mailboxes.But seeing that offline defragmentation rate is only 6-7 GB / hour and its a down time. My plan is create new storage group and move all mailboxes to new storage group. After moving all the mailboxes delete the old storage group.
Plan for free up database white space:
Create new Storage groups and move mailboxes and delete old storage groups.
1. Create new storage group A on E: move all mail boxes from First storage group (old) to new storage group delete the old storage group.
2. Create a new database B on F: move all mail boxes from Second Storage group ( old) to new storage group and delete old storage group.
3. Move back A storage group from E: Drive to F: Drive.
I believe this will help us to free up the white space on the old storage group.
one more thing I want to clarify .If I am moving all mail boxes from a database having 100 GB size ,with white space 50 GB to a new database .
The new database size will be 50 GB or same like the old database (100 GB)
Thanks in advance
