TW file in AC15 but it's Hotlinks are AC14?

[rob2218]

What would be the best way to translate up 2 hotlinks which were created in AC14, yet the main file (where the two hotlinks are connected) are in AC14.

What would the procedure be for updating the 2 hotlinks?

Keep in mind the following:
1) Main file in AC15 has about 12 stories.
2) Two Hotlinks have same number of stories but only certain information has been drawn on certain stories.
3) Would I need to repath EACH and EVERY story individually into main file (AC15) once I convert the two Hotlink files into an AC15 TW file?
4) All 3 files are Teamworked and all three files are hotlinked into each other in one fashion or another.

Needless to say...it's a bit complicated.
Suggestions most helpful.
