Neil,
   The short answer is probably "merge the two databases manually and
rebuild the index". I don't think there's any real answer otherwise.
Given the old version of MySQL you aren't going to be able to do
anything fancy like federating the two tables to into another database
and making a view out of the two or anything.
   Actually the only other possible alternative is to do a myisam_ftdump
- -s on both databases and get the Average Global Weight for each database
and then use one to "normalize" the results from the other, reading...

http://www.databasejournal.com/features/mysql/article.php/3512461

...states the the query weight (final score) also depends on the local
weight but that's okay (I think). So, er, right...

To get the approximate query score for database 1 from a score retrieved
in database 2 multiply it by the Average Global Weight of db1 divided by
the Average Global Weight of db2. I think, it's a bit late ;^). Hence...

The approximate database one Query Score = database two's Query Score *
(database one's Average Global Weight / database two's Average Global
Weight)

A) It is only an approximation, IT IS NOT accurate. Your mileage will
vary depending on the similarity of the contents of the two databases.
B) Get a second opinion on that.

Try it and let us know how well it works.

Regards,
        Phil
