Hello.
I'm new to VirtualBox. I have been using VMWare Player for years and now I have decided to migrate to VirtualBox.
I was able to open my VMDK files in VirtualBox but I have a question: should I convert them to VDI using VBoxManage?
What are the advantages of doing this?
Thank you.

Yes you should, the advantages being that (a) we have expertise here on how to repair damaged VDIs, not so on non-native formats, (b) there are a number of features such as resizing and compaction which only work on the native format - VDIs.

And given that you can always convert the medium back to VMDK in the future, I can't see why anyone would hesitate.
