Dle

Good afternoon.
Need to upgrade dle from 10.6 to 14 version.Looking for a specialist who is familiar with the theme of the movie websites.
Need upgrade version dle preserving the functionality of the modules. The main problem is slow loading because of the clutter of already unused modules and crutches in the code "to work."
The second problem error internal linking in the form of address.net./123
Possible further cooperation on the website.
