This document describes the upgrade procedure for StackState.

Determine the type of upgrade

There are several ways of upgrading StackState, depending on your configuration setup and the changes in the StackState release. Please read the StackState release notes carefully before starting an upgrade.

If you are using the StackState application and have not installed any StackPacks, or are using StackPacks that have not been upgraded in this release, follow these steps:

  • Create a backup
  • Upgrade StackState
  • Verify the new installation

If you are using the StackState application, have installed StackPacks and are planning to upgrade one or more of them:

  • Create a backup
  • Unstall StackPacks
  • Upgrade StackState
  • Install StackPacks
  • Verify the new installation

NOTE: when you upgrade a StackPack, any changes you have made to the templates in that StackPack will be overwritten.

Create a backup

Before upgrading StackState it is recommended to backup your configuration and topology data. The script bin/sts-backup.sh will create a backup and store it inside the backups/ directory.

NOTE: the StackState backup can only be restored in the StackState and StackPack versions prior to the upgrade.

Uninstall StackPacks

StackPacks that are going to be upgraded must first be uninstalled. This removes all StackPack configuration from StackState.

NOTE: the StackPacks must be uninstalled using the version of StackState prior to the upgrade since this version can contain different installation logic from the new StackPack version.

Upgrade StackState

Depending on your platform, you can use one of the following commands to upgrade StackState:

  • Fedora, RedHat, CentOS:
    • using RPM: rpm -U <stackstate>.rpm
    • using yum: yum localinstall <stackstate>.rpm
  • Debian, Ubuntu:
    • using dpkg: dpkg -i <stackstate>.deb
    • using apt: apt-get upgrade <stackstate>.deb

Install StackPacks

StackPacks that have been upgraded can now be installed again. This provisions StackState with configuration information from the new StackPack.

Verify the new installation

Once StackState has been upgraded and started, verify that the new installation of StackState is reachable and that the application is running.

Version-specific upgrade instructions
