When I am trying to upgrade service manager 9.33x to 9.50, I am getting attached error message.
What's your exact upgrade path ?
What source do you have ? SM9.3x with which PDCP applied ?
What's the target you want to upgrade to ? SM9.50 Codeless or Hybrid?
The Upgrade Guide lists on page 40 the Supported Upgrade paths (https://softwaresupport.hpe.com/km/KM02588594) .
Supported from SM9.3x to SM9.50 is :
Source: Process Designer Content Pack 9.30.3 (PDCP4) applied
Target: SM9.50 Codeless
Source: 9.3x system that has Process Designer Content Pack 9.30.2 (PDCP3) applied.
