I haven't used the product before so I have no information about data loss.

Again, I recommend that you contact CMJ support directly with those questions.

Snapshots created on versions of Jira before Jira 6.3 will remove transitions. How aboout snapshots created after JIRA 6.3  do we loose any data.  Any idea about data loss exporting from version 8.13.1 to Data Center Jira of 8.20.6.  In this case would we encounter any loss/issues?

You should probably contact CMJ support directly with that question.

I don't think this is a CMJ issue though. It is about the changes in Jira. CMJ is not providing a product designed to be able to support what you want to do. They can't possibly create a product that would accommodate the changes in Jira versions in such a way that they could guarantee no data loss when you tried to use it to move date between different Jira versions. They would have to test every combination of different Jira versions.
