I get this error trying to import components from another 7.0 ELM server using this command:

repotools-ccm -scmImportComponent adminPassword=********** adminUserId=clmadmin fromFile=C:\media\exportComponents.tar importContributors repositoryURL=https://mytargetserver:9443/ccm

Both servers are Windows 2016 with ELM 7.0 (no iFixes). The original server is DB2 11.1 and the second is DB2 11.5. Does that matter? Does everything have to align 100% the same?

And the root cause is an SQL error:

Caused by: com.ibm.db2.jcc.am.SqlSyntaxErrorException: DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC=BLACKBOARD.DEFERRED_ITEMS, DRIVER=4.26.14

I have tried this many times, but keep getting this error. Is this a defect?
