How does copying work for IFS Cloud environments hosted by IFS?

Hello,

We have noticed that some of our customers' data is not included when IFS recopies environments (e.g. PROD to UAT).

In fact, our customer had a system parameter which was present in the PROD environment, but which did not appear in the destination environment after the recopy.

I'd like to know whether IFS performs a dump when recopying or whether a script excluding certain tables is executed?
If so, can you provide us with the list of tables excluded during recopying?
Thanks in advance.
