Overview
This chapter covers the instructions on installing, updating, and migrating QAD QXtend using the stand-alone QXtend installer. If you are going to install QAD QXtend on QAD EE 2016 with YAB, see Installing and Updating QXtend Using YAB.
The QAD QXtend installation disk contains the QAD QXtend installer, which supports GUI and character-based installs, upgrades, and migrations.
The QAD QXtend installation, upgrade, and migration options are as follows:
• Install, upgrade, or migrate in a GUI environment using the QDCS.
• Install or upgrade in a character environment using the QDCS. You first run the installer in a GUI environment to populate the QDCS with the required settings. See Installing, Upgrading, and Migrating QAD QXtend in a Character Environment.
Note: You must have completed a successful installation before attempting to migrate the QXI servlet, QXO database, or QXO events database components.
The QXtend adapter, QXO servlet, and QXO server are code-based. There are no upgrade routines for these components and they are installed in place of the old version.
