DSXchange

In previous version we used to have stand alone file in encrypted format (partially readable) for SDKSequences but in 91 i found a directory with name SDKSequences in project folders with two sub directories as DATA.30 and OVER.30

Storage of SDKSequences is different in 9.1 as compared to 8.1 or 7.5.
How to migrate 8.1/7.5 SDKSequences to new 9.1 server?
