how to convert 4.x configuration to 8.x ???

[Dirk Nerling]

Hello,

I do have a named (4.x) config with some virtual domains and so on. Now I
have to use bind 8.x. The former (4.x) doesn't work - I get

May 16 14:07:04 pcfx named[1495]: limit files set to fdlimit (1024)
May 16 14:07:04 pcfx named[1495]: /etc/namedb/named.boot:1: syntax error
near ;
May 16 14:07:04 pcfx named[1496]: Ready to answer queries.

Does anybody know an tool to convert my named configuration???
best regards and thanks in advance
