To upgrade to the latest version:
Download the latest update (delivered as a .zip file).
Navigate to the System tab of the Smartcrypt Enterprise Manager.
Click Choose File from the System Updates section and select the .zip file you downloaded in Step 1.
Click Update. The update will be applied and the system will automatically restart. Some updates will take longer than others and you may need to wait up to 15 minutes for an update to be fully applied.
There are two Appliance update .ZIP files. The first one contains OS package updates and the second one contains Smartcrypt Enterprise Manager application updates. Operating system updates must be applied before the Smartcrypt Enterprise Manager update.
Note: If you are upgrading to an 18.X from a 17.X Smartcrypt Enterprise Manager, you must first be on 17.7.43, apply the OS update, and then apply the Smartcrypt Enterprise Manager 18.X update. Note that these updates may cause the appliance to restart more than once.
Updating software on a cluster
If you are updating an appliance cluster, update the master first, then slaves that replicate directly from that master, then slaves that replicate from the first set of slaves, etc.
Note: Upgrading the master causes a publication of the compatibility matrix between all slaves. All nodes will evaluate themselves and decide if they are compatible or not. If they are not, they disable their service API (clients cannot connect to them) and they send a message stating that they are not compatible with the cluster. Each slave must be upgraded; after which they will rejoin replication. Slaves may be updated ahead of the master. For example: If the master is on v17.0 and a slave is on v17.1, the slave will operate at the v17.0 feature-set until the master has been upgraded to v17.1.
