CMS Made Simple Forums

Hi CMS forum,
Quick question....
I'm helping out a friend with a very old CMS implementation, version 1.8.2.
I know the upgrade has to be done and will be planned. However, the hostingprovider wants to migrate the website to a new environment with PHP8.1 on it and for the short term I wnt to know if this will be compatible untill I can find the time to upgrade the site.
Any thoughts?
Regards!

No, it will not work. CMSMS 1.8.2 was released in 2010, at which time PHP 5.2.x was current. If you upgrade the 1.x series as high as possible (1.12.2) you'll probably still have to go with PHP 7.x, although it's possible just the frontend may work in 8.x depending on the modules and tags used.

If you'd like the upgrade done sooner, check out the hire-a-dev link in my signature.

Thanks for the repyl, I was afraid of this.
So I will start with the upgrade and work through that before migrating the webiste to e new hosting environment
