I don't undestand your excitement... :-)

You have three (vinum) drives on three seperate (physical) disks. On 
these drives are several concat-plexes. Nothing here violates the 
requirements for the GEOM-based vinum, if your old vinum-type 
partitions don't start with an offest of "0" (zero) within the slice 
(da0/da1) or disk (ad0) respectively.

*If* that's the case (i.e. Offset of 0 for the vinum partitions), you 
have a problem indeed but otherwise I would not expect any problems.
