Is there documentation on REST API differences for JIRA server vs JIRA cloud

[Stephen Deutsch]

There should be basically no differences between (the latest version of) Server and Cloud.  For older versions of JIRA, check the differences between the /latest documentation and your particular version:

I disagree. I have just hit a difference - you cannot expand properties on an issue search with server rest, but you can in cloud rest ... 

why ?

OK. So that means after we do some work to integrate a local APP with JIRA Server version(mostly getting data from JIRA through REST API), it should automatically work with JIRA cloud version if we choose latest version of JIRA, right?
