Prior to Upgrade

If you have any UNIX Engines that share a common installation directory, you must migrate those installations to a local directory. A shared install point is no longer supported.
To enable programmatic version control, ensure that gridLibraryStrictVersioning is set to false.
If you have a Linux64 Engine, for upgrade from all versions earlier than 7.0.0_hotfix08, you must perform the following steps:
a. Stop the server.
b. As a best practice, take a backup of the existing engine.sh file.
c. Replace the engine.sh file from the engineScriptUpdate folder to datasynapse/manager/webapps/livecluster/engineUpdate/linux64/ and datasynapse/manager-data/engineUpdate/linux64/ folder.
d. Start the server.
e. Let the Engines log in and then restart the Engine Daemon.
f. Stop the server.
g. Upgrade the server.
Note: In case of Grid Architecture, perform the steps from step a to step g on the Primary Director.
