Upgrading from 4.x to 5.x

[rdesgagn]

I currently have Overleaf-CE version 4.2.0 running in a Proxmox VM. I now need to upgrade it to the latest version 5.5.1.

1. Is it as simple as running the upgrade script in the bin folder ?
2. MongoDB version is 4.4 with Overleaf-CE 4.2.0. MongoDB 4 has reached end of line in Feb 2024. Do I need to upgrade that first before running the update script ?

Thanks for your help,

René

MongoDB version is 4.4 with Overleaf-CE 4.2.0. MongoDB 4 has reached end of line in Feb 2024. Do I need to upgrade that first before running the update script ?

Yes, I'd suggest looking into the release notes for Mongo upgrade instructions: https://github.com/overleaf/overleaf/wiki/Release-Notes-5.x.x

Is it as simple as running the upgrade script in the bin folder ?

We test it in Ubuntu environments only. It would be great if you can leave feedback about the upgrade experience in your environment.
