Hi Gour,

yes there is.  Basically, you will use bogoutil and a bit of shell stuff

1. stop the mail system so that you don't confuse it

2. for each user, run bogoutil of the sqlite3-enabled version:

cd ~
bogoutil -d .bogofilter/wordlist.db >.bogofilter/wordlist.txt

3. replace the sqlite-based bogofilter by the BerkeleyDB-based
bogofilter install

4. for each user, do this:

cd ~
# backup database:
mv .bogofilter/wordlist.db .bogofilter/wordlist.db.sqlite3
# re-import database:
bogoutil --db-transaction=yes \
	-l .bogofilter/wordlist.db <.bogofilter/wordlist.txt

(there should be no blanks after the \, or you remove the \ and put the
bogoutil ... and the -l ... parts on the same line).

5. restart the mail system

That should be all.  Test a bit and if you are confident that everything
works as desired, you can remove the wordlist.txt and
wordlist.db.sqlite3 files.  Or you keep them as backups :-)

This is a generic procedure, only the --db-transaction=yes is specific
for conversions into BerkeleyDB-based format.  For all other output
formats, just omit --db-transaction=yes.

HTH,
Matthias
