Moving to new server, need help planning upgrades

Using Neos & Flow Installation & Deployment
1

New server is ROCKY9 running PHP8
Old server is CentOS7 running PHP7.4

Neos installation running fine on old server, but hasn’t been upgraded…
Tried moving webs & data to new server, get PHP8 errors…

I guess my strategy should be to iterate ‘upgrade in place’ on live server till i get to the version that’s PHP8-compatible, and THEN migrate the web&db to the new server.

I found a big stack of upgrade instructions (Neos Upgrade Instructions - References - Neos CMS - Neos Docs) but not sure how to check what version we have running now ( is there a command for that?

And can someone please advise me which version I need to get to, in order to be PHP8-compatible?
new server is running PHP 8.0.13

TIA ! :palm_tree:

PS!! are these upgrade instruction referring to the ‘Framework’ version? Or Applications version? Or Sites Version? Or Libraries??

I just found the /neos/administration/packages page, and I have a real mishmash of versions listed there… most (but not all) Applications 4.3.17 , framework 5.3.22 , (many libraries 5.3.22 as well), Site is 5.0.2 …

For php 8.0 you need at least Neos 7.3 and for php 8.1 you need Neos 8+. I know no way around an Neos update.

Thanks Martin! I’m still wondering how to find out exactly which “version” I need to start the upgrading process from…

There is a version matrix here:
