Upgradeing from Duo to NV+ - using the old 2TB disks

I had a ReadyNas Duo with 2 x WD20EARS (a 00MVWB0 and a 60MVWB0 - they had matched but one was replaced under warranty)

I have just upgraded to a NV+ (agonised over the V2 for ages but I don't need the higher capacity etc)

I 'build'the NV+ with 2 x WD20EARX-008FB0
Hot added the WD20EARS-00MVWB0 from the Duo and let it sort itself out (overnight) - all was good.
This moring I hot added the WD20EARS-60MVWB0 and let it sort itself out - it's just finished and, again, all is good.

So I now have:
Ch 1 : WDC WD20EARX-008FB0 [1862 GB] 1859 GB allocated
Ch 2 : WDC WD20EARX-008FB0 [1862 GB] 1859 GB allocated
Ch 3 : WDC WD20EARS-00MVWB0 [1862 GB] 1859 GB allocated
Ch 4 : WDC WD20EARS-60MVWB0 [1862 GB] 1859 GB allocated


Fingers crossed it stays good - and that this info is helpful for others.
