On Windows 2012 Server, we have Harvest 7.1 SP2 32bits.
When we run Upgrade.exe from Harvest 12.6 DVD we get this message:
"Harvest old version found. This version is not supported to upgrade from this utility"
- Harvest 7.x and 12.5 / 12.6
As there is no 64 bit support for 7.1.x installation, during upgrade process it is necessary to use 32 bit installation of r12.5. You can migrate to the 64 bit r12.5 after upgrade is successfully completed.
Upgrade.exe on our Harvest 12.6 DVD is only for upgrades from 12.0.x or 12.1.x to 12.5 or 12.6
In order to upgrade from 7.x, you need to get https://ftp.broadcom.com/user/downloads/pub/ccc/harvest/r12.5/upgrade_7.1_X_to_12.5/win32/Upgrade.exe
