OpenVZ Migration Hostnode Containers from Centos 5 to Centos 6 -

OpenVZ Migration Hostnode Containers from Centos 5 to Centos 6

migrating from an old OpenVZ (Centos 5) to new OpenVZ (Centos 6)
Also if migrating from 32-bit HN to 64-bit your RAM will probably be much bigger than it should be!
16x bigger

eg. 32bit HN:

             total       used       free     shared    buffers     cached
Mem:           256         16        239          0          0          0
-/+ buffers/cache:         16        239
Swap:            0          0          0


eg. 64bit HN with same config:


free -m
             total       used       free     shared    buffers     cached
Mem:          3906         42       3863          0          0         33
-/+ buffers/cache:          9       3897
Swap:        28614          0      28614
