I have a client with a server that was set up prior to us taking over their IT needs. The previous IT created a C drive with the size of 40GB and a D drive with well over 1TB. Needless to say C drive is perpetually out of space and I would like to increase the size. The rub here is the D drive is setup as an extended partition so I am not able to rob space from there to put on the C drive. I'm not liking my options after some researching online. I am concerned about data loss and downtime. There is a good backup happening nightly but at the same time I need to limit the downtime. Any suggestions as to how to handle this and impact the customer the least?
