ISaGRAF 3.5 Compatibility with ISaGRAF 3.32 
Upgrading from ISaGRAF 3.32 to ISaGRAF 3.5 
To upgrade an installed version 3.32 of ISaGRAF to version 3.5 you may install overtop of 
the older version or choose to uninstall ISaGRAF first. 
Installing Overtop of ISaGRAF 3.32 
This is the better choice because it allows you to keep all your current projects restored. 
1.  Install ISaGRAF Workbench 3.5. 
2.  Install ISaGRAF Extensions. Even if the version of the ISaGRAF Extensions has not 
changed, it must be re-installed after installing the Workbench 3.5. Any version of the 
Extensions may be installed with ISaGRAF 3.5. 
3.  ISaGRAF will run in demo mode for 30 days. Use a Hardware license key or select 
Licensing from the ISaGRAF 3.5 program group to enable a permanent software 
license.
