Newbie and the replacelist command

I've had to change from one supplier of majordomo services to 
another. Supposedly, the new supplier is offering the newest version 
- 1.94.5

With the previous supplier, I was able to use a replacelist command 
which is very helpful because I run email forums with a totally 
different registration every third week.

When I try this command with the new supplier, I get the message that 
this command is not recognized.

I'm not sure where else to get the information but hope you can help 
because I'll need it or something similar quite soon.
