Yes. There is no need to migrate projects from Paratext 8 to Paratext 9. However, there may be a few small inconveniences when working with a shared project in both versions.
- If the project includes figures, the markers for these may appear different in Paratext 9 than in Paratext 8, and it may be hard to edit figures in both versions.
- If the project uses Ruby glossing (a special need for Japanese language texts), these glosses may not be visible for Paratext 8 users.
- When creating a new project in Paratext 9, you can create it using USFM3 or USFM2. Paratext 8 does not fully support USFM 3 but it will open such projects.
- Certain project plans may only be applied and edited in version 9. However, the progress is shared between both 8 and 9.
