Hey team, absolutely love your work on this great modpack - thank you for your efforts.
We used to run AOF5 on aternos and started back with v1.5.x. As it seems that our original legacy world is causing all sorts of oddities as well as aternos isn't really good enough to run this pack we decided to go with our own paid PebbleHost server and maintain the server ourselves.
This being said, would it be possible to get some instructions or best practices from you devs on how to do server version upgrades the best possible way? Would like to keep up with your great work and enjoy the latest and greatest but in a controlled manner. Thank you a bunch.
P.S. Thought I share one hacky idea we are planning to use while "moving over". We plan to pack all our stuff in large chests, wrap those chests in cardboxes, taking all cardboxes in player inventories and then transferring the playerdata files to our new server. Then when you log in to the new world you have all your stuff with you (also you location so be mindful of this). We hope this works and maybe someone else might find this useful too. We accept to loose our buildings but loosing all the stuff is a bit too much. Cheers.

Would be a good doc addition for all server operators.. funny stuff always happens when upgrading a server.. ie. ASAIK, World terrain generation y level changed 3 blocks back when Notch still was rocking indie development.. Did not turn out very well with existing structures.. ohh the memories..
