Migration from MF ALM Synchronizer 15.5 to MF Connect Core 4.5.

Hello everyone,

We are planning to migrate from MF ALM Synchronizer 15.5 to MF Connect Core 4.5.

ALM Synchronizer 15.5 is used to synchronise Defects between ALM and IBM Clearquest. I would like to know if anyone has already done this combination "ALM - MFConnectCore - Clearquest" (or knows about it) ? and if they can give me any information (or links to docs) about the "MFConnect Core-Clearquest" link?
Is there a connector to add to make this link?!

Thank you very much for your help
