Hello All,
We're replacing our v3170 with new gear (two clusters) and making the leap from 8.1.3 in 7-mode to 8.3 CDOT.
I have a couple of questions around migrating our vFilers to the new cluster.
Converting 32-bit aggrs: I see several places in NetApp's documentation saying the only way to convert in 8.1.3 is to expand the aggr to more than 16TB and it will happen automatically. I see references online to CLI commands that will set this off without needing to cross the 16TB line, and other references saying this is not recommended by NetApp or is even unsupported. And yet I have a co-worker here who converted a vFiler here when it outgrew 32-bit and swears a) expanding to 16TB did not spark the conversion and b) the CLI tool worked just fine.
What is the official way to convert 32 bit to 64 bit?
Second: how widely used is the 7-Mode Transition Tool? Got a candid opinion on how likely it is to be a better option than copying volumes by hand?
Hope to hear from you,
Randy
Randy -
Hi, you can convert aggregates from 32-bit to 64-bit with the following commands, however it is completely unsupported.
First check if there is sufficient space in the aggregate to convert them:
'priv set advanced' 'aggr add aggr1 -64bit-upgrade check'
Then run the conversion (requires elevated privileges):
'aggr 64bit-upgrade start aggr1 -mode grow-all'
Then check status with:
'aggr 64bit-upgrade status aggr1 -all'
Regarding data migration, 7MTT works fine for CIFS/NFS shares however doesn't cover LUN migrations. The best way to facilitate LUN migration (if that is your goal) is with the DTA2800 appliance (https://library.netapp.com/ecm/ecm_get_file/ECMP1236758). There are of course other host-based methods work as well (Storage vMotion, LVM mirroring, etc.)
I wasn't clear from your wording which you're trying to migrate (file data or block data) so I hope the info provided is helpful.
Best of luck!

With 7MTT 2.0 and ONTAP 8.3, 7MTT will do block / LUN migrations (albeit offline).

Randy -
For the official method, you convert the 32-bit aggregate by adding disks such that the size of the aggregate exceeds 16TB. The procedure is explained in this KB (https://kb.netapp.com/support/index?page=content&id=1014790&actp=RSS) and commands are listed below:
Identify 32-bit aggregates and run a check to see if the volumes are sufficient: filerA> priv set advanced filerA*> aggr status filerA*> aggr add aggr1 -64bit-upgrade check
Perform the upgrade and add disks: filerA*> aggr add aggr1 -64bit-upgrade normal 12
Monitor the status of the conversion: filerA*> aggr 64bit-upgrade status aggr1 -all

Just to add a few points
I haven't seen it documented in many places but in order to go from pre 8.2.1 to 8.3 if you have 32 bit aggregates then you need to do a stepwise upgrade, upgrade from pre-8.2.1 to 8.2.1, convert all the aggregates to 64 bit and then upgrade to 8.3 as 32 bit aggrs are not supported in 8.3.
If you mirror from a 32bit aggregate to a 64 bit aggregate the 32 bit aggregate is downgraded to a 32 bit aggregate while the snapmirror is active. On breaking the snapmirror the 32bit destination aggregate is converted back to 64bit. (YOu can see this in the messages log)
We have done a number of 32-64 bit upgrades on 7-mode but did have one instance where during the upgrade of one of the volumes in the agggregate to 64 bit it became inconsistent and we had to mirror the volume back from another site to recover the data.

Hi Randy,
After reading this list for some time now I am excited to respond with first hand information we had going through a similar transition.
This was for CIFS not block but we used the transition tool extensively to automate the tasks of migrating volumes to a new CDOT filer (albeit 8.2.3 CDOT not 8.3). We liked the transition tool very much it made managing the migration very easy.
This also has ramifications for migrating to 64-bit aggregates. We had several volumes that were 32-bit volumes/aggregates that we also transitioned with the tool. The tool sets up snapmirror relationships between the source and new filer and they must keep the volume as 32bit. After the final cutover for any volume we migrated the volume then went through a background conversion to 64-bit. I could not find this documented anywhere in the transition tool documentation (though I might have just missed it) but this process happened on several volumes without any issues at all.
