I install two new serwers (6.5.3) and made cluster. I changed administration server to one of them. When i move person from R6 server to this cluster all is OK. But when i move person from R5 server, mail box is create only on first serwer. Databases admin4.nsf and names.nsf is replicated without design changes (on R5 servers has R5 design).
Problem was described in post
