upgrade EHP7 ->EHP8 upgrade ERP, application servers need to be upgraded?


I would have a question related to upgrade to ERP EHP8. If upgrading a system ERP on EHP7, having already 745 release kernel to ERP with EHP8, is it required that the application severs connected to central instance need to be reinstalled after the upgrade? Or the application servers only have to be started normally after the upgrade is completed?

Kind regards,

    Hi Manu,

    the reinstallation of the additional application server is only needed for release 6.40 (according to the latest SUM guide).

    What you have to consider is that the SAP profile parameter DIR_PUT is the parameter used to define the directory in which temporary data is stored during the update. If you perform an update with additional application server instances, make sure that:

    • The value of the SAP profile parameter DIR_PUT matches the current <update directory>/ abap.
    • The parameter DIR_PUT is known to the additional application server instances.
    • The additional application server instances have read/write-permission for the <update directory>.

    Best regards,
