The logs have prolly been created when you moved the mailboxes from one server to another.
What is the average number of log files generated per day ?

If Exchange1 database is empty, you can delete the logs and activate circular logging.

Regarding 115Gb, the database can not shrink, even if it's not hosting any mailboxes. You must run eseutil /d to shrink it or it will always keep its max size.

Finally, it's safe to remove this database if you are done with your migration to server exchange2

when you ran backup what option did you choose? for the exchange logs to be deleted you need to select "full" backup instead of just "copy". so please run backup again with full option. this should get your log files deleted and free your disk space.

now we still need to find out why still you have such a large database on that server. are you sure, you moved all mailboxes?

well, all in all it really sounds a bit strange. is this only mailbox server role? or do you have cas/hub also on one or both of these boxes? how is your mail flow? through server 1 or 2 or a different one?

The_KirschiCommented:
Actually Gerald26 is correct about the mailbox database size itself. The database does not free up space on the disk but only within the database files themselves if you delete any items or in your case move the mailboxes off. You need to do an offline defrag in this case:

http://www.msexchange.org/articles_tutorials/exchange-server-2010/management-administration/eseutil-part2.html

Of course in your scenario you should be safe to dismount and delete the mailbox store on server 1 so you even don't need to fiddle around with eseutil.

Run a full offline backup, dismount database first.

confused guys

im running full vss backup "Backup Once option"
after that what should i do ?

Gerald26Commented:
This database is going to be deleted because you dont need it anymore. You can just dismount it and save it offline. Do not save logs as full EDB will allow you to restore the database as it is now.

After this offline backup, you can delete logs, and remove database.

F_A_H_DAuthor Commented:
so first i will take the full backup
then i will dismount the data base
then remove the database
finally delete the logs


correct this order ??

Gerald26Commented:
dismount , backup the files ,remove mailbox database from exchange THEN you can delete both edb files and logs
database MUST BE dismounted for offline backup

F_A_H_DAuthor Commented:
i left the database enabled as it is after that i enabled the circular logging on that database after that i run full backup it saved huge space now i have 123gb free disk space

"i don need this database at all im preparing exchange1 for format"


what i did was correct ???

Gerald26Commented:
You're welcome.

But I hope you know that if the two exchange servers are in the same Organization, you can not jsut 'format' the old one. You must remove it correctly from active directory and do some modifications on address list generators, connectors, websites and so on.
I can not explain it all here, but I just can not let you being in a messy situation because you didnt do it correctly.

when you're done , you can turn off your old exchange server for a week and see evrything is going normally. then you can format it.

Do not rush !

correct
i tried to switch it off for one day and i met some problems like
the outlook users every 10 mins user name and password windows prompt them
also when any one launch the outlook it gives him security and security error that the name on the certificate doesnt match
also i can feel some slow

any way its another issue but please if you have any documentation or explanation in how to shut down this servers please provide it to me

Ill try to find some documentations, but it requires a really good knowledge of AD and Exchange, a little knowledge of powershell and some IIS knowledge as well.

You will want to do it step by step

Cas migration -> Site, certificates, addresslists/oab, everything else related to client connexion including autodiscover configuration and rpc over http (outlook anywhere)

Hub Migration -> routing groups, receive and send connectors, antispam, rules and all this stuff

Mailbox --> you're already quite good with it, maybe some public folders to migrate

F_A_H_DAuthor Commented:
i will consider all thoose points
but if i uninstall the exchange through control panel add/remove programs it do the necessary uninstallation from the AD ?
0
 
Gerald26Commented:
It won't let you kill it that easily :) Exchange will check if everything is ok before you can uninstall it.

The program wont delete the configuration from AD because the new exchange needs it ! It will just remove some objects. In fact, you don't even have to worry about AD.

Just really focus on the 3 roles (I think you don't use UM role do you ? )

You can do it without blocking the production, users must not even notice you're working on the servers.

i think gettings this user name and password prompts and the security error because of the certificate .... exchange1 has real certificate and exchange2 has self certificate
in this case i should transfer or should do new installation ... what u think ?
0
 
Gerald26Commented:
It's a normal behaviour with a new unconfigured cas server. Wait for tawthe to reissue a new certificate based on your new server CSR.

I think we should close this case and start another after you get your certificate, or this thread is going to increase infinitly since there is so much to say about Exchange :p
