Upgrading PHP

[LandyVlad]

My 2.0.15 forum is still running on PHP 5.6

My host has recommended that I upgrade it (to make it more efficient in processing so my site isn't slowing down), and no doubt it's overdue.

So

1. What PHP version should I upgrade to? 7.1? (I gather 2.0.15 isn't 7.2 compatible, but 2.0.16 will be?)

2. What actions/changes (if any) do I need to do to ensure it all still works properly when I upgrade?

Thanks

All mine are running fine on 7.1 but I probably run different mods on my sites, it would depend if all your mods are happy on 7.1 etc. SMF itself is fine.

Aside from changing the PHP version on the hosting account what else do I need to do SMF wise? - if anything.

How do I know if mods will work on PHP 7.1?

I didn't think @mention members worked on anything above 2.0.7

Yes, SMF 2.0.15 will run fine on PHP 7.1. You can use a mod that will allow you to use 7.2 but it gives errors it your error log. You can just delete the errors but AFAIK there's no other problems I'm aware of.

There may be problems using certain mods, however.

Most mods that far back will still work with 2.0.15 as not much has changed in the database, just coding changes. Read the support topics for it to see if there are any changes you may need to make. Otherwise, you should be able to "emulate" it when installing it.

IIRC The first version of SMF I installed was 2.0.13 and I've upgraded twice from there.

@mention members has always worked for me flawlessly. It's a great mod, but obviously its built into 2.1 so I wouldn't bother introducing to any 2.0.x forum at this point.
