Migrating to a lower Node Count

$

0

We have a system currently with 6 + 1  1TB nodes in a BW scale-out scenario.

With the new capabilities of Haswell Processors and the increased Memory/CPU ratios,

we are looking to Migrate to a 4+1 1.5TB node cluster.

 

So question is how to do the Migration? This will obviously be a homogeneous migration but with the reduced node count

backup/restore methods will not work.

 

So is this an export/import method or is there some other method for doing the migration that I have not yet come across.

 

 

Cheers
