The hard drive where Exchange 5.5 is installed now doesn't have enough space, so I need to move it to the new drive in the same box. My questions are:

1. Is it possible to install Exchange 5.5 in the new drive, move mailboxes, and uninstall Exchange 5.5 in old hard drive? If yes, please reply me a detail steps.
2. I already did run optimizer and it didn't help much. How can I move all mailboxes complete to the different drive without installing the server in the new drive?

Thanks.

What does your drive structure look like?  Is everything on C: or is Exchange on a different drive?

This won't be very difficult at all.

OK, do you want to replace C with the new drive or just move the Exchange data off to a new drive?

The problems with reply email signatures

Do you wish that you could place an email signature under a reply? Well, unfortunately, you can't. That great Exchange/Office 365 signature you've created will just appear at the bottom of an email chain. What a pain! Is there really no way to solve this? Well, there might be...

Sorry that I didn't make myself clear in the question. I have Exchange server in C: drive and a new drive F: is already installed in the same box. I ran the optimizer once a while ago over F: so F: has excsrv folder created.

I'm not so clear about the Exchange server structure, so I'm not sure whether I can install Exchange server in F:, move mailboxes from C: to F:, then uninstall Exchange server from C:. If yes, is there a tool that I can use to move the mailboxes from C: to F:?

OK, so you pretty much want to move all of your Exchange data from C to F then.  Running perfwiz (optimizer) and selecting the new drive as the destination for various files on the last screen is the recommended way to go.

Here are some of the files you'll be moving and their recommended paths:

Private information store \exchsrvr\mdbdata\priv.edb
Public information store \exchsrvr\mdbdata\pub.edb
Directory database \exchsrvr\dsadata\dir.edb
Directory logs \exchsrvr\dsadata\*.log
Information store logs \exchsrvr\mdbdata\*.log

Also, here are some other data sources, but I wouldnt move them:

MTA \exchsrvr\mtadata
Internet Mail Connector \exchsrvr\IMCDATA

Don't try to move these files manually.  Like I said, perfwiz is the way to do this.  You can also do it through Exchange Admin, but perfwiz is what you should use.

I would leave the MTA and IMC in place.  There are some performance implications.  Most people put database files on a RAID 5 array or better.  The logs are usually stored on a separate mirror (RAID 1).  Not everyone has the resources to do this, but it is best for performance, especially when supporting hundreds of mailboxes on a single server.

I don't want to move the data, I need to reinstall Exchange server in the different drive (F:) and uninstall Exchange server completely from C. What could be the installation procedure without loosing any data?

Please do this at your own risk.  It's not hard if you know what you're doing, but making a mistake will cause trouble.  Make sure you have a backup.

First, I would hesitate to move the Exchange binaries from C:.  They take little space and use nearly no disk I/O.

Again **MAKE SURE YOU HAVE A FULL BACKUP**

Know what service pack version and hotfixes are installed before you start.  If you don't, upgrade to the latest and go from there.

Uninstall Exchange

Reinstall Exchange

Replace the new exchsrvr\dsadata\dir.edb with the dir.edb from the original drive.

Do the same for exchsrvr\mdbdata\priv.edb

Do the same for all other files in exchsrvr\mdbdata to catch any logs in case you didnt shut down gracefully.

You'll have to reconfigure your connectors and a few other settings that are stored in the registry.
