Workaround

1. In splunk, find the affected build number

   {	[-]	
     	 @laas:	{	[+]	
     	}	
     	 @timestamp:	 2017-11-08T01:33:44.854Z	
     	 ctx:	{	[+]	
     	}	
     	 ec2:	{	[+]	
     	}	
     	 env:	 prod-east	
     	 ext:	{	[+]	
     	}	
     	 host:	 ip-10-124-137-59.useast.atl-inf.io	
     	 hostname:	 fe02da372311	
     	 level:	 ERROR	
     	 location:	{	[+]	
     	}	
     	 logger:	 cloud.atlassian.upgrade.core.DefaultUpgradeTaskFactoryProcessor	
     	 m:	{	[+]	
     	}	
     	 message:	 Cannot downgrade as there is an upgrade task for factory (host) and build number (73011) that has not completed	
     	 pid:	 32	
     	 product:	 jira	
     	 thread:	 pool-53-thread-1	
     	 time:	 2017-11-08T01:33:44Z	
     	 timestamp:	 2017-11-08T01:33:44,854Z	
   }
   

2. Search for the upgrade history id in entities.xml file that has the affected build number
   example:

   <UpgradeTaskHistory id="10005" upgradeTaskFactoryKey="host" buildNumber="73011" status="FAILED" upgradeType="SERVER"/>
   

   <UpgradeTaskHistoryAuditLog id="10005" upgradeTaskFactoryKey="host" buildNumber="73011" status="FAILED" upgradeType="SERVER" timeperformed="2017-10-31 10:47:00.097" action="upgrade"/>
   <UpgradeTaskHistoryAuditLog id="10100" upgradeTaskFactoryKey="host" buildNumber="73011" status="FAILED" upgradeType="SERVER" timeperformed="2017-11-01 16:35:25.813" action="upgrade"/>
   <UpgradeTaskHistoryAuditLog id="10200" upgradeTaskFactoryKey="host" buildNumber="73011" status="FAILED" upgradeType="SERVER" timeperformed="2017-11-01 17:42:36.14" action="upgrade"/>
   <UpgradeTaskHistoryAuditLog id="10300" upgradeTaskFactoryKey="host" buildNumber="73011" status="FAILED" upgradeType="SERVER" timeperformed="2017-11-01 17:48:13.427" action="upgrade"/>
   <UpgradeTaskHistoryAuditLog id="10400" upgradeTaskFactoryKey="host" buildNumber="73011" status="FAILED" upgradeType="SERVER" timeperformed="2017-11-02 19:28:45.587" action="upgrade"/>
   

3. Remove that from the entities.xml file
4. Zip backup file
5. Perform JIRA Restoration
