I was having my site in shared hosting, I took the entire backup, its structure is like

addons          homedir        mysql             resellerpackages  suspendinfo
bandwidth       homedir_paths  mysql.sql         sds               userconfig
counters        httpfiles      mysql-timestamps  sds2              userdata
cp              locale         nobodyfiles       shadow            va
cron            logaholic      pds               shell             vad
digestshadow    logs           proftpdpasswd     ssl               version
dnszones        meta           psql              sslcerts          vf
domainkeys      mm             quota             ssldomain
fp              mma            resellerconfig    sslkeys
has_sslstorage  mms            resellerfeatures  suspended

Now I have subscribed to vps, I have copied the files inside homedir/public_html to var/www/html of my new hosting, but am seeing the following error when I view it browser,

There has been an error processing your request

I have just created database with name magenhto inside mysql. Previously I had cpanel and used one click installer. Hence am not aware of how to use that data inside mysql to this new system and are there any more changes.
