We have 3 business critical applications, running on BL870-i4, millions
of lines of code, mostly cobol, porting effort estimated in tens of man
years. 3 production clusters, 3 others for disaster recovery, 3PAR
storage with inter-site replication, etc. Not the kind of stuff that 
can
easily be migrated to another platform. And we also have stability and
reliability requirements that other platforms cannot entirely meet.
We already have long term plans to migrate to OpenVMS X86 in a couple 
of
years.
