Hi @changgengzhao and the Novartis team, welcome to the OHDSI community.
There have been a couple prior threads about support for CDM conversion.
In the forums, you can search the prior discussions to relive the
conversations. Here’s a link to one that may be useful for you:
CDM conversion vendors. I know there are
others in the community providing groups like yours support, so will let
them chime in as well.
Cheers,
Patrick
