Upgrading OpCenter

If a later version of OpCenter software is available, an OpCenter instance can be upgraded even if jobs are currently running.

Before you begin

Any jobs in a transitional state (initializing, floating, resuming, suspending, or capturing) block an upgrade. Either cancel those jobs or wait for those states to pass.

Procedure

Log in to OpCenter by entering the following command from a terminal:
```
float login -u admin -p <admin_passwd> -a <OpCenter_ip_address>
```
where <admin_passwd> is the admin password and <OpCenter_ip_address> is the OpCenter's private IP address if you are within your organization's virtual private cloud (VPC), or public IP address if you are outside the VPC.
Note: Only the admin user can upgrade software. Upgrades cannot be executed from the web CLI shell.
To see what version of OpCenter software is currently running, enter the following command:
```
float version
```
To see what versions of OpCenter software are available, enter the following command:
```
float release ls
```

If a later version of the software is available, upgrade the OpCenter instance by entering the following command:

float release upgrade --release <version>

Note: If --release is omitted, the latest version of the software is selected.

Example:

float release upgrade -r FLOAT_v2.5.0-b12f1d2-HalfMoonBay.bin
Warning: There are running jobs in server, do you want to upgrade forcibly?
Some jobs may fail if you do that!(yes/No): yes
Warning: Are you sure you want to upgrade the system to (FLOAT_v2.5.0-b12f1d2-HalfMoonBay.bin)? (yes/No): yes
OpCenter is now upgrading and will be online soon.
Pause briefly and then log back in

After executing a software upgrade, check that the upgrade succeeded by entering the following command:
```
float version
```
If the OpCenter upgrade is successful, upgrade float to the same version by entering the following command:
```
float release sync
downloading ...
the float binary is synced up with opcenter
```
