Hi, I got ask my uncle to help with his super old web site and it is running on 1.0.15 version. I've never worked with Modx but I do have programming background. From this article
https://docs.modx.com/revolution/2.x/administering-your-site/upgrading-modx/upgrading-from-modx-evolution it seems like upgrading seems like way bit tricky.
For one the modules might be a problem but I only see Doc manager there which seem to be maintained.
Unfortunately I don't see any backup options so I might have to do the database and files backup by hand.
