Required Installations for Upgrading
For a safe and orderly upgrade, at least four Actian X installations are needed:
Original version production installation
Original version development installation
Installation for testing the upgrade
New version development installation for preparing and testing applications
If possible, keep the installations away from the production machine. You may temporarily need additional hardware to accommodate the required installations during the upgrade.
