You can upgrade the database file using the Developers Edition of SQL Anywhere 16.

REM If you're a command-line kinda guy, here is my template Windows 
REM batch file run_dbunload_upgrade_v5_to_v16.bat. It does the 
REM unload-reload-all-in-one-dbunload-step, then starts dbeng16 
REM and dbisql so you can make sure the new database is up and running.

REM Be sure to stop *all* database engines on the computer you're using, 
REM before starting the upgrade.

REM dbunload...
REM -an ...  where to put new database
REM -ap ...  new database page size
REM -c ...   old database startup connection string
REM -o ...   where to put unload console display text file
REM -v       verbose mode for console display

PAUSE MAKE SURE YOU DO NOT HAVE ANY ENGINES RUNNING.
