The bad part is , I don't have login credentials to that server, and it's pretty much very old server and has lots of data. So I wanted to virtualise it without losing any data . Is there any ideas how I can convert it to vm to run in esxi6.1 ?

While a P2V does appear possible, this doesn't help the problem with lack of logon credentials..

Hi, thanks for replying. Is it possible to do by taking the harddisk out ?

Do you know how to do a P2V conversion with a vmware environment ?

No, I have never done any conversion, this is one of my new project in a new work. So am just wondering how to start.
