For general server requirements and other information related to upgrade, please refer to SD 8.0 Implementation Guide .
1. General pre-upgrade considerations for ServiceDesk 8.0:
This failure is simply noting the fact that the required version of Workflow is NOT installed. Clicking "Next" is the correct choice so that the correct version of Workflow can be installed. Same problem will occasionally occur with ServiceDesk 8.0 HF1 installer (but generally only with a Warning).
2. When upgrading from ServiceDesk 7.x to 8.x do not upgrade Workflow by running Workflow installer manually. Always upgrade Workflow using ServiceDesk installer.
If Workflow server is upgraded manually Portal may not function normally.
3. Upgrading ServiceDesk from 8.0 HF1 to 8.0 HF2
4. When upgrading from ServiceDesk 7.5, 7.5 MP1 or 7.5 SP1
Beginning with version 7.6 Workflow engine relies on .NET Framework 4.5. Therefore .NET Framework 4.5 needs to be installed, ISAPI and CGI restrictions must be set to Allowed for Isapi filters of ASP.NET v4 and all Application Pools (at least processManagerPool and ServiceDeskPool or Application Pools running Workflow and ServiceDesk applications) should be set to .NET v4.0
See TECH233602 for related info.
If you have a large number of processes, you will want to budget time for the date/time conversion to UTC values.
5. Migrating from releases prior to ServiceDesk 7.5
In-place upgrade is not supported if you are on version 7.1 SP2 or earlier and migration process involves moving to new hardware.
