Conversion of 32-bit aggregates to 64-bit

Naveenpusuluru

Hi Techies I am planning to migrate all the luns and volumes from my legacy 7-mode systems to new cluster mode systems. But my 7-mode system is running on very older ontap version and also it has 32-bit aggregates. Can you guys please let me know how to proceed with it. Please find the details below.

 

7-mode ontap version : 7.3.2

7-mode box model : FAS3020

 

c-mode ontap version : 8.3.1

c-mode box model : FAS8040

 

Do i need to upgrade the 7-mode ontap version to 8.1.4 + to perform this conversion of 32-bit aggregates to 64-bit?

A FAS3020 can't run anything newer than 7.3.7.  Foreign Lun Import could bring the LUNs over without requiring the 64bit conversion on the source.  Other options include host/application based migrations (Storage vMotion, etc) or doing an intermediate headswap to a controller that can run 8.1.4P4.

Hi @SeanHatfield

 

Can you please send me the process of Foreign Lun Import.

Just about everything you could want to know is in TR-4380

It was also the topic of a recent Tech ONTAP podcast:
