ObjectScale 1.3 upgrade considerations

If you upgrade to ObjectScale 1.3 from an earlier release, be aware of the following effects of new features on existing configurations. Contact Dell Support for ObjectScale upgrade from version 1.2.x to 1.3.0.

Table 1. Upgrade considerations for ObjectScale 1.3
ObjectScale 1.3 new feature	Upgrade considerations
Replication of S3 delete markers	In previous releases, the S3 delete marker in versioned buckets was not replicated. In this release, the destination bucket includes the DeleteMarkerReplication setting. You can configure this setting to ENABLE or DISABLE delete marker replication. Be aware of the following effects on existing policies: In upgrade situations when a policy was defined in an ObjectScale version earlier than 1.3, the XML files for the older policy do not include the DeleteMarkerReplication setting. The default behavior in this case matches the DISABLED setting. If you edit an older replication policy after installing ObjectScale 1.3, you must add and set a value on the DeleteMarkerReplication setting as part of the editorial change. You can set it to ENABLED or DISABLED. For consistency with how replication worked in your prior releases, choose DISABLED.
Support for larger multipart uploads (MPUs)	ObjectScale 1.3 supports MPUs for objects up to 50TiB in size and up to 50,000 parts. Upgrade considerations include: ObjectScale 1.3 significantly increases efficiency, reduces timeouts, and reduces memory usage in MPU processing. It is acceptable to start uploading parts in ObjectScale 1.2 and continue uploading parts for the same object after an upgrade to ObjectScale 1.3. The maximum size of replicated objects also increases to 50TiB when both the source and destination are upgraded to ObjectScale 1.3.
