SCUP 2017 RTM - No publications imported from SCUP 2011

[gmandar 1]

Hello All,

I am running SCUP 2011 and its working fine. Since SCUP 2017 is released, I installed on the same server where SCUP 2011 installed. Since the install paths are different, there is no option for upgrade but luckily post install it detects exsiting SCP 2011 setting and prompts to import which I done.

After checking in SCUP 2017, I found that Published updates status is not imported from SCUP 2011 showing publication date blank and Publication workplace is empty. 

• Does that mean that I have to re-create the publication and assign updates to it for earlier published updates from SCUP 2011?
• Will SCUP 2011 and SCUP 2017 can co-exist?
• What is the implication if I published those same updates from SCUP 2017 as well? Will they appear double in SCCM post syncing?
