It sounds like you have to shutdown Asterisk, find the old voicemail 
messages stored on the server in their respective directories, and 
convert all of them to the new file/audio format, then modify 
voicemail.conf and then re-start Asterisk. At least that's what it 
sounds like to me. In other words, it seems that Asterisk will get 
confused if it finds old voicemail messages in the storage with a format 
different from what voicemail.conf tells it to expect.

I suppose if you go and delete all the old voicemail messages before 
changing the format in voicemail.conf, it will work equally well. 
However, your users might not be very pleased :-)
