Re-allocating CNFS Buffers - best way to do so?

[avon at bbs.geek.nz]

When I set up my INN server I had allocated a number of large cycbuff to various metacycbuff

I now find that I really should have changed the allocation of how many cycbuff were assigned to each metacycbuff

The current setting is

metacycbuff:BIG8:BUFF01,BUFF02:SEQUENTIAL
metacycbuff:ALT:BUFF03,BUFF04:SEQUENTIAL
metacycbuff:BIN:BUFF05,BUFF06,BUFF07,BUFF08:SEQUENTIAL
metacycbuff:CTCALL:BUFF09,BUFF010:SEQUENTIAL

As I don't really carry any binaries (and had set this configuration up much earlier in the process before this dawned) I was to use some of the cycbuff currently assigned to BIN and move them to the other metacycbuff.

Sometime ago I recall stopping the server and changing the allocation of cycbuffs assigned to metacycbuff but then hit issues with permissions to write to cycbuff or similar. Can't recall. 

What is the best way to reassign cycbuffs to different metacycbuffs?

In the case of the cycbuff I want to look at each has a minimal amount of data written to them (68.4 MB, 1.6MB, 1.6MB, 1.6MB)

TOTAL: 10	-	500.0 GB	23.0 GB	4.6%	0	0.67	-


Thanks for any advice guys :-)
