I am in a very tricky situation.
My current Nextcloud is on v25.0.10 on a Turnkey Linux LXC in Proxmox.
I would like to move my installation to All-In-One which is on 27.0.1.
I’m pretty sure I’m not getting upgrade notifications for 26 and 27 in my Turnkey Linux because I have PHP 7.4 installed and 8.1+ is required. Therefore, I can’t upgrade it.
I tried just copying my database and data directory to All-In-One but it says I need to update.
I don’t know how to update my Turnkey Linux installation so that I can upgrade Nextcloud before moving it to All-In-One. Or maybe there is another way. Any suggestions appreciated.
