i read in a not so far past that it was a bit risky because of some kind
of bug with iManager 2.02, and a detailed step by step procedure had to
be followed to avoid to destroy the rest of the S2S configuration..

is it safe now with iManager 2.5, using the latest BM38SP4 plug-in, on a
BM38SP3 master and NW65 fully patched ?
