One more about local copy of site ...
Do know the distro of the hosted platform? Ubuntu/CentOS and version?
If so, on your PC, run VirtualBox ... setup a guest OS Ubuntu/CentOS that is as close as you can get to the hosted.
Clone your production site ... the 2.9.x ... to the VB Guest OS ... now you can practice updates and upgrades.
Your local then would be the same environment (or very close) - minus tools like cPanel (that's $) but one could run Webmin (free/open sourced 'cpanel')
You would be in total control then ... so when provider/hoster says we can't do that ... ?????
