No. They are not compatible.

When you install 5.1.2, it will do a conversion of the database or you can import your most recent backup, which I strongly encourage you to make in either case. With 5+ databases, you can also create your database using a SQLite backend which will be the new standard in the next (5.2??) major release.

If you intend to use both machines to edit your data, you should devise a strategy to copy XML backup or exports from one machine to the other, and re-import each time.  If you do it this way, both versions of Gramps can continue to work.  It would still be best if you upgraded Gramps on the 4.2.8 machine, there have been a lot of improvements and bug fixes since then.

Trying to use the actual db files between the two machines is usually a recipe for disaster.  You did not mention the OS for the machines, since the Windows AIO has used the same version of the bsddb database for quite a while now, it might actually work, until you make a mistake in syncing your data, or forget to close Gramps on one machine while working on the other.

For two different versions of Linux, it probably won't work at all, as the bsddb versions are not likely going to be the same.  Gramps would try to upgrade on one machine, and then the other would be unable to open the files.

If you try sharing the db files, please make sure that you make frequent backups, at least use the 'backup at close' feature.  So you have a recent backup when the db gets corrupted, and can no longer be read.
