Again in the position where my source aggregate is 32 bit and destination is 64 bit and this prevents vfiler online migration.

Last year this was a priv set diag command

aggr 64bit-upgrade start aggr1 -mode grow-all

In test mode, this completed the 64 bit upgrade quickly and without error.

Anyone done this in production? (Ontap 8.1)

thanks
