Note!The staging directory should not be the same directory as the one you created and set up as the MZ_HOME directory. |
Place the *.tgz file from your release delivery into the staging directory.
Use a command line tool, go to the staging directory, and unpack the *.tgz file by running the following command:
Code Block $ tar xvzf <filename>.tgzA directory is then created in the staging directory, containing the software to be installed. For the purpose of these instructions, this directory is referred to as the release content directory.
Now copy the MZ license file into the release content directory.

If you are upgrading from 8.3.x, you need a new license file. Contact DigitalRoute Support https://www.digitalroute.com/contact/contact-support/ on getting the MZ license file. |
