If you are looking to certify, Global Knowledge has a good boot camp that covers CS1k, Session manager and touches on system manager.
I was going to take it, but found the “Implementation and Upgrade” was more advantageous to my current role. Here are the boot camp labs, looks like some cool stuff.
Lab 1: Upgrade an existing CS 1000 Release 6.0 IP Peer Network to CS 1000 Release 7.5 integrating Aura
Lab 2: System and Aura Session Manager
Lab 3: Enable UCM services on the Avaya Aura System Manager
Lab 4: Migrate the UCM primary security server database to System Manager
Lab 5: Migrate the CS 1000 NRS database to the Avaya Aura Session Manager
Lab 6: Upload CS 1000 applications to the deployment server
Lab 7: Perform one-touch upgrades on CS 1000 6.0 Linux servers to 7.5
Lab 8: Load software on Linux-based servers using NFS
Lab 9: Enable and configure SIP Line Gateway and SIP clients
Lab 10: Deploy and provision IP Media Services
