Migrate profiles and creating mod collection, list, or package (zip) in Vortex to use in new GoG install of FO4 - Steam migration

[fishmantx]

Ok, I'm going to be migrating all my FO (and all my other) games to GoG and off of Steam. I've purchased and download my entire collection of games (those that were available) from GoG as installables to my hard drive. Part of this is migrating to a 6T from a 2T drive that is now full. An older ver. of Vortex is my mod manager and that's not going to change due to W7U pc. I have a limited working knowledge in Vortex, just enough to install mods and set rules and load order. Other than that I'm a danger to myself. ;oP PS. I have already "Steamless"ed all my executables except Halo MCC until the migration to GoG, so technically, I'm off Steam already. I will be adding FO4 London.

PC Win7 Ultimate (NO I'm not changing this until I migrate to Linux)

Questions:

1. What is the best way to migrate a profile and saves from a current game to the new "platform" (GoG)? Other than just changing target folders? Or can I ?

2. Pretty sure all mods will have to be reinstalled, so how can I create a collection, list, or load pkg in RAR to preserve my current mod list and configuration in Vortex to use in the new GoG game platform? I have created a collection for "upload", which I don't intend to upload, but was hoping to add to my own collection, but see no path to do so. It's only a list after all. I have already copied all mod RAR/7z files to a backup folder on my drive, but that's a lot of lost space to a probably unnecessary redundancy. I intend to clean up the mod list to remove many failed and/or undesirable mods before deploying into GoG FO4

3. I currently have two working character saves, but will be reenabling profile management to use multiple character profile names for different purposes. Mostly construction and a mod test bed. With multiple profiles/character names, do I need to install the mods for each or is it a "communal thang" across all profiles for the game in question when profiles NOT enabled? Reason to ask is that with profile mgmnt enabled "Fish" has all the mods and "Ivan" has none, BUT with Ivan active and profiles off, it loads all the mods for FISH?!? How did that happen?????

Ivan's world is heavily modified and at level 147 with HUGE amounts of construction and I fear dragging the weird little symbol over to the Ivan profile from Fish that it'll screw it up. I think this happened because I started a new game named Ivan with the Fish config installed and later went into Vortex, didn't see it, only Fish, and pulled it up in Vortex via "Savegame". Suddenly all the "Fish" mod config was being used on Ivan as default! If one reenables profile mngmt, Ivan is empty of mods. Weird.

Like I said..a danger to myself at this point....

My current working assumptions are.....

1. I'll need to remove / uninstall all undesirable mods in Vortex before deleting Steam (preferable) or at least before installing GoG FO4.

2. All mods to be retained will have to be fully reinstalled from scratch. Not holding breath that Vortex will redeploy into the new platform from the current list.

3. Current savegames may not function in the new FO4 after migration.

Thanks for the help guys. Direct me if I need to ask these questions elsewhere.....

Figured out item 3, but what I found was WEIRD.
