Since backups are made to .tar.gz files, is it possible to backup using the h-sphere control panel and restore using cpanel, directadmin and vice versa.
Now if one is changing web hosts with different control panels, can one backup up a few GB of webfiles from the 1st web host to the root of the 2nd web host, and use the 2nd web host control panel to restore files?
It is not that easily done as each control panel has a different setup.
Using the root WHM transfer system, you can transfer accounts from servers running WebPanel, Plesk, Ensim, and Alabanza. I'm not sure what the deal is on the DA or HS sides as far as transferring accounts over to there.
It may be easier to just setup a new account on whatever system you want, then archive of all your files in your public_html directory (or wherever your files are stored) on the old server, then move that over to your new server.
