Ah, sorry, I somehow missed that your plans have changed.
Where before you had one project, now you have two: 1) Upgrade v1 to v3, and 2) Migrate Scrivener to a new PC.
If it were me, I would:
- Do the upgrade from v1 to v3 on my old PC and confirm the projects all look perfect.
- Migrate my v3 projects to the new Win11 PC.
See this post from @RuthS of L&L support for a bit more detail. Also, my post upthread links to the Knowledge Base article on migrating v3 to another PC.
Best,
Jim
