Cpanel trial / demo licenses are not limited in features or other limits ...
The only limitation on those is just that they will be expiring soon!
Regarding your missing files transferring, it is likely one of the following:
1. Some of the files may have been owned incorrectly by the user
named "nobody" instead of the account owner login name. This is
most common when using image gallaries or CMS systems on the
web hosting account when the server is setup as Apache DSO based
PHP scripting engine instead of using SuPHP or PhpSuExec.
** The solution is to update the ownership of the web hosting files:
Code:
chown -R username:username /home/username/public_html/*
2. Old log files (particularily large files) sometimes don't get transferred
when transferring or backing up web hosting accounts. Take a look
at the log files under /usr/local/apache/domlogs to see if this is the
files missing from your transferred account.
