You can perform major and minor nondisruptive upgrades when deduplication is enabled, provided that no more than 500 FlexVol volumes have deduplication enabled and that no deduplication operations are running during the Data ONTAP upgrade.
The total number of deduplicated and non-deduplicated FlexVol volumes must not exceed the total number of FlexVol volumes supported for nondisruptive upgrades on your system.
