Recently I have been tasked to downgrade our BizTalk Non Production environment as it was running on BizTalk 2016 enterprise. After all the backups I then uninstalled BizTalk 2016 enterprise and installed Biztalk 2016 developer edition I then configured the BizTalk server to join the existing BizTalk databases for the Group and features such as SSO and Business Rules engine and finally I restored the master secret. I made sure that these features were part of the installation.
After that I opened the console everything seems to be in order except for when I import/export a policy
adding a policy
I restarted all the services I could think of, rule engine service, WMI, DTC, the server itself to no avail. I even checked the Business Rules Composer and I could see all our policies/vocabularies. I checked the Registry and I could see BizTalk and BusinessRules entries and couldnt find anything different from a working environment(the one I have not touched yet)
So here I am wondering if anyone have encountered this issue and how did you solve it?
The answer lies in this blog post that Colin Dijkgraaf have commented - manishrules.wordpress.com
Root cause The table dbo.adm_Group in the BiztalkMgmtDb - somehow the values for RuleEngineDBServerName and RuleEngineDBName disappeared when I uninstalled the BizTalk Runtime for the downgrade, even worse the DateModified column didnt get changed.
Fix I inserted the values for the columns mentioned and its now fixed
