Question: What is ECS CAS missing that Centera customers should be aware of?
Data shredding is not available currently in ECS CAS. As of 3.0 all Advanced Retention Management (ARM) features such as event-based retention, litigation holds, and the Min/Max governor are available. NOTE: ARM features are available for CAS only.
Question: What does the Transformation engine do?
The Centera Transformation and Migration feature allows organizations to natively (within ECS software) and seamlessly migrate ECS-compatible applications to ECS from Centera. The practically non-disruptive application cutover allows data to be moved as a background process. As of 3.0, migrations can be administered using the Web UI.
Question: Are there any caveats to migrating data from Centera to ECS?
Yes. ECS Sync and Datadobi migration tools cannot migrate Centera legacy data to ECS without disruption to existing EBR and/or LH information. ECS's built-in transformation engine does support migrating Centera legacy data with EBR and/or LH.
