It looks like I may need to migrate my server.
My virtual server has 50GB on C and 250GB on D partition and I only have 2 GB left on C which is forever reducing because of winsxs. I can only increase C if I backup all my data and reimage the server then change the partition sizes and then copy back all my data.
I currently host 50 website and this, I expect will be a massive job as I believe I will have to reconfigure my IIS settings for all of the domains, I am really dreading doing this so looking for the most painless option.
so I could do as suggested above or just migrate site by site to a new server.
Any other suggestions?
You should be able to down the server and edit it's virtual settings and then just resize the drive, then boot back into windows and resize the partion using disk management or disk part.
