Factorio Forums

I dunno how many people have already upgraded to the latest version, but maybe there are too few whom haven't yet to make tweaking the migration mod worth it, but would be nice if it could pre-set the long-handed replacement inserters to their one tile out configuration to match the old long-handed inserters they replace. I had a rather large built up factorio empire and a lot of my production chains broke until I tracked down each one to reconfigure it to the long-handed pickup/drop it had previously with the long-handed inserters. Thanks!

That's what the Inserter migration mod is for.

Basically though... for it to work, you have to install the migration mod, load, save, then update, as per the instructions in the migration mod.

It wasn't possible for the migration mod to be built into the logistics mod, because it requires running a lua script first, then a json migration, but the game runs all json scripts before lua scripts.
