Replicator V2
Hello all,
My NAS gateway code will be updated from 5.5 family to 5.6 family, and the replicator will be updated from V1 to V2.
Could anyone advice:
1. Will the replicator conversion be started automatically once Replicator V2 license is enabled ?
2. If the answer is No to 1, can existing replications be converted one at a time ?
3. Will there be a chance to specify MaxTimeOutOfSync value per replication session as part of the conversion ?
4. What are the lowest possible value for MaxTimeOutOfSync ?
Want to see if flexibility is available to see how Replicator v2 works on testing data before changing production replication sessions.
Thanks,
Victor

great answer from Gustavo as always
I just wanted to add that of course you can change the the RTO value later on.
From what I've heard the actually RepV1 to RepV2 conversion is actually done by EMC support, but that may vary from country to country

1. Will the replicator conversion be started automatically once Replicator V2 license is enabled ?
No. During an upgrade to NAS version 5.6, if any file systems, VDMs, and/or iSCSI configured replication sessions are found, or if Replicator V1 is enabled, the Celerra will remain configured for Replicator V1. If the customer has only iSCSI replications, their Celerra will be configured for Replicator V1. If not already done, you can enable Replicator V2 on each Celerra by running the deploy_replication utility and manually switching the license to Replicator V2.
2. If the answer is No to 1, can existing replications be converted one at a time ?
No. Replicator V1 and V2 sessions cannot co-exist.
3. Will there be a chance to specify MaxTimeOutOfSync value per replication session as part of the conversion ?
High water mark and ¿to¿ on the source and destination is replaced by ¿max_time_out_of_sync . During the conversion from RepV1 to RepV2, the value is equivalent to ¿to¿ on the source side. If ¿to¿ is equal to zero, the conversion script creates the V2 replication with the manual refresh option instead of specifying the ¿max_time_out_of_sync value.
4. What are the lowest possible value for MaxTimeOutOfSync ?
It ranges from 1 to 1440 minutes.
