Hello,
We are running ERP on EHP6 and planning to upgrade component GLTRADE from 600 to 606, to enable some functionality as per Business need.
As per the SUM guide we have noted down all known issue and solutions for upgrade and download all necessary patches by using Maintenance planner.
For this upgrade we are planning to use SUM SP 14.
Source version: EHP6 AIX+DB2 GLTRADE 600
Target Version: EHP6 AIX+DB2 GLTRADE 606
As per SUM SP 14 note 2084104, it has mentioned to upgrade the SAP host agent to minmum patch level 7.20 203, where are we are running host agent on 7.20 186.
My queries are below:
1. Do we need SAP application downtime to upgrade SAP hostagent or we upgrade SAP hostagent on the fly no downtime is required ?
2. I have 8 application server, then in this case do i need to upgrade SAP host agent on all application server ?
3. Does is mandatory to upgrade host agent, can start upgrade without upgrading the SAP host agent ?
Regards,
Anil
