I am trying to upgrade from 5.9 to 5.17 with SQL Server database and I am running into some issues. 5.17 upgrade complains that ACT_HI_VARINST and ACT_HI_IDENTITYLINK are missing. Some of the fields (e.g image datatype) remain as is (image datatype is now changed to varbinary).
Is upgrading from 5.9 to 5.17 valid/ possible? or, do we have to upgrade to an intermediate version and then upgrade to 5.17?
TIA
