This topic describes the upgrade offline-disk-store command in gfsh, the VMware Tanzu GemFire command-line interface.
Use this command to upgrade offline disk stores from the format used in Tanzu GemFire releases prior to 10.1 to the segmented disk store type introduced in Tanzu GemFire version 10.1. See Defining and Configuring Disk Stores for more information about the benefits of segmented disk stores.
If the disk store is large, additional memory may need to be allocated to the process using the --J=-Xmx### parameter.
Availability: Offline.

upgrade offline-disk-store --name=value --source-disk-dirs=value(,value)*
[--destination-disk-dirs=value(,value)] [--segments=value]
[--max-oplog-size=value] [--J=value(,value)*]
