Centera cannot migrate clips over 100 MB to the ECS. This is by design, it is CAS SDK behavior which stops taking additional tags once CDF crosses 100 MB. Although a raw-read is successful on the Centera, the file read on ECS fails.
The clip must be directly written from the application to the Centera and then migrated once more to ECS. This generates a new clip ID. The new clip must be updated on customer application database. It may have to be stored with previous clip ID which can cause read errors.
