Hoping someone can help out with our little project this weekend with our server. And can help us avoid the nightmare of simply everything everyone's ever worked on turning to sand.
So, basic background info.
We set up a Tekkit server back in the good old days when the bukkits roamed free, and the world seemed so full of possibilities.
We updated to the most recent version ofTekkit Classic in the whole Classic/Lite division because we had no desire to lose Railcraft, one of the most commonly used core mods on the server. We also uninstalled EE and that naff weapon mod at the same time since it just didn't fit well with our world, and reinstalled crafting Table III (Since it works fine wih Tekkit, only causing occasional clent side crashes if you click in the wrong place).
Now, here's where it gets complicated.
After some considerable time with no updates, we ended up manually installing Mystcraft, since there was no sign of us getting a new Tekkit update soon. Took an afternoon but well worth it.
Recently we've looked into updating to Tekkit Lite, since we've got a couple of mods we're interested in (Okay, one mod, Modular powersuits) and would like a few bits of post 1.2.5 vanilla content, as well as up to date versions of mods like computercraft that see a lot of use.
Now, we want to ditch adding any other mods (None of that popular thaumcraft nonsense, no thermal expansion, no factorization) basically we just want to keep the core Tekkit Classic mods (Particularly the most used ones, Buildcraft, Redpower, IC2, Ender Storage, Computercraft) plus add the other mods we have on our server that we're so invested in (Railcraft, Mystcraft)
Our biggest worry is something breaking either our buildcraft piping systems'o'doom (We use them for SO much) or all our Railcraft stuff (It'd take FOREVER to fix everything, you know how long it takes to make everything in Railcraft, and it's not like we're going to have time to boot up the server, hop into creative and rebuild it all from scratch) OR most importantly, breaking our Mystcraft books. We have hundreds, and most crucially, they're all kept in a library INSIDE A MYSTCRAFT AGE. So if we lost access to it everyone loses all their worlds.
Is there a way to limit incompatibilities when doing a transfer like this, so that we get to keep most of our world? Reinstalling Crafting Table III after the fact was easy enough since we only lost a handful of those, but losing something like our Railcraft stuff or any of our piping would be a disaster we might not be able to recover from. All sorts of stuff would be destroyed (Literally, in some cases. We'd have exploding machines all over the place due to cooling systems failing). So as you can see we'd want to make sure the mods were all working compatibly before booting the server and leaving it up.
