Here is an excellent step by step of how to do this from Dragon32
(1) Ensure names of old version of mod and new version are different.
(2) Copy new version into Data Files
(3) On Mash's mods tab change load order so new version is right next to old version.
(4) On Mash's mods tab right click new version and choose Updaters
(5) Select old version of mod, Mash lets me know if my save game needs updating
(6) If it does head on over to the Saves tab and select appropriate save
(7) Right click the old version in the list of mods associated with the save game and choose Change to...
(8) Select new version of mod
(9) Click Save
(10) Back onto the Mods tab and deselect the old version and select the new version
(11) Delete old version from Data Files
(12) For completeness, run a Repair All against the save game
Congrats, very interesting mod, I will try it ASAP :goodjob: .
Just an advice on your Mash updaters info: I think you have the word "new" and "old" inverted in step (4) and (5)
I believe you are correct
I will get on to changing that right now.
Actually, it's the right way round. http://wrye.ufrealms.net/Wrye%20Mash.html#UsinganUpdatedVersionofaMod.
