In a four Lim system , it would be easier to
make a new 3Lims system .
If you are veeery careful lim4 can be removed (BC10-BC12).
By removing all data .
Move common function programs ,the proper way.
Kill the lim , after taking a backup of system
on a spare hdu as 4Lims system first(if anything goes wrong you can revert).
If the system is BC9 or lower lim4 can't be removed
caused by the common split unit DEMC ,
as this can't be moved to i/o lim or
lim2 that has DEMA or lim3 that has DEMB in it.
Removing DEMC from the system can't be done as this
gives corruption cause it holds neccesary data .
So in this case a new buildt 3Lims system is the only option .
A DEM.. unit can only have one instance of it in a lim.
And it can't be placed in i/o lim .
In a 4lim system it's distributed like this:
Lim1 None
Lim2 DEMA
Lim3 DEMB
Lim4 DEMC
So there is no place to move the DEMC to.
From bc10 DEMA-DEMZ is replaced by one unit DED
so that problem dont exist .
