I have a shared account in DH
An I Want to know if I can upgrade to Dedicated Hosting?with my same account..
Or dedicated is separated and I need to open another account?And will I need to move files, configurations, to new package?
You can upgrade your account, same web-id and all. When I asked DH was also going to give me a credit for any 'time' left with my current plan. I think that they will also carry over your files for you.
You'd be best off to double check with support about it though to make sure.
I'm not sure that they have any dedicated servers available right now. I asked a few months ago for a couple and they said no more until "the end of the year"
I think I heard something in this forum backing that up as well.
You can upgrade tho yes
