Can a boot partition be merged with another?

I have recently took over remote administration Dell server.  It has two RAID arrays, RAID 1 for the OS and RAID 5 for the data.  It's running Windows 2003 Server, and is fully patched.  

The problem I have is that either Dell or the people that set it up partitioned the mirrored array so that it now holds C: and E:, and C: is already too small for the OS, and this box has been in service only a few weeks.

Currently E: has Dev Studio and MySQL installed on it, both of which can be reinstalled if needed, and C: has the OS.

I'd like to merge C: and E:.  Can that be done with a boot partition or would I have to wipe and start over?

You cannot do this while the system is booted.  You will need an NTFS boot disk as described here: http://searchwincomputing.techtarget.com/originalContent/0,289142,sid68_gci1126671,00.html?topic=298540.

NB: I have not personally vetted this procedure, so all usual caveats about "please make sure you have good backups in place before trying this" apply.

There may be third-party tools that can merge partitions on a server, but I'm not specifically familiar - I used to use Partition Magic but that was only designed for desktop systems without RAID arrays.

Hope this helps.

If configured properly, you don't need all too much space for the OS. How large is C:\?

C: has between nine and ten gigs of space (I forget the exact number).

That's enough for the OS.

Just make sure no 3rd Party software that isn't installed by the OS is installed on C: (uninstall such software and reinstall to another location).

Make sure you don't have your pagefile on C:

Limit the size of the eventlogs.

Make sure user profiles etc aren't on C:

Change the location of any Temp directories to another drive.

Clear internet Caches.

Delete \windows\system32\$NTUnins... folders or move them somewhere else. These are made by windowsupdates so you can uninstall such updates. If the updates work that isn't necessary... (I usually leave them for a couple of weeks after the updates were installed, and when satisfied things work I delete them). On a new system you shouldn't need to roll back any updates.

Make sure your backup software and others don't write any logs or other files to C:.

Empty the recycler.
