Hi,

I am using hysqldb 2.4 only with my split database see:
https://www.mediafire.com/file/59iq0esx071zcic/Split_HSQLDB_Wizard_v3c.odb?ssl=1
for a bit of background on my setup.

So, I do not think that there is any problem with having both 2.4 and 1.8, as
1.8 is used only for the embedded database.

IMPORTANT BTW, I have been using my split database since about 12/15/2017 and
have had no hanging/crashing problems at all.  I have more than 30 hours of
using it and entering data.  I have had some "fun" making it do the right thing
(like auto-incrementing keys in tables) but I have fixed my particular
problems. I miss being able to modify database tables after they are in use. 
(Yes, I can setup a new one, copy-paste data and then delete the old one.)  But
the rock-solid stability makes these annoyances a very minor problem.  So, I am
interested in spending my limited time, particularly on the computer, working
instead of chasing bugs.

I would seriously suggest that "official" and updated documents be written for
Base concerning CONVERTING an embedded database to a split one.  Currently,
there are a number of sources (SEE ATTACHED PDF) that are from different dates.

I would also suggest that NO ONE use an embedded database because of the
numerous problems discussed in various forums and articles on the web.
