The 1st of January 2020 will see the SAP support backbone upgrade completed. This will bring support for HTTPS communication between customers ERP systems and SAP’s Support backbone. This upgrade will affect the way SAP Solution Manager transfers information to/from Solution Manager.
All SAP Solution Manager 7.1 systems are technically outdated and cannot communicate with the updated SAP support backbone. Hence, an upgrade to SAP Solution Manager 7.2 SP stack 7 or 8 is required.
If you are on SAP Solution Manager 7.2 SP stack 6 or lower then plan to update SAP Solution Manager 7.2 to SP stack 7 or 8 as soon as possible. No further action is required.
You are already well prepared if you plan to go to SAP Solution Manager 7.2 SP stack 7 before Jan 2020. SAP plans to enable SP stack 7 with SAP Notes to leverage increased security
SAP will provide more information on the planned SAP support backbone update in Q2 2018.
