Is it possible to convert a basic disk to dynamic disk without losing data in Server 2008?

Question

I am not able to extend partition in windows server 2008. We have two different partitions which we want to join and make one partition. I came to know that basic disks have limitation of 2 TB each partition and we can create a maximum of 4 partition due to limitations.

Solution

Yes, your data will be fine, though you should always ensure your backups are maintained and up to date before doing such critical operations.

Here is a Technet article which will guide you through the process and some key considerations:
