Upgrading Concert on a VM

You can upgrade IBM® Concert on a virtual machine. For the upgrade, you use the installation package that includes scripts and utilities for you to operate an updated version of the Concert services.

To upgrade on a virtual machine:

Download the latest package of the Concert software, replacing <version> with the latest available version number. This package is also available on the Concert GitHub repository.
```
wget https://github.com/IBM/Concert/releases/download/v1.0.1/ibm-concert-std.tgz
```
Go to the directory where your current version of Concert is installed.

Set the following environment variables to the values that you set during the original installation:

export DOCKER_EXE=<docker or podman>

export CONCERT_REGISTRY=<your registry>

export CONCERT_REGISTRY_USER=<your Concert registry user>

export CONCERT_REGISTRY_PASSWORD=<your Concert registry user password>

Stop all Concert services:
```
./ibm-concert-std/bin/stop
```
Confirm that services are stopped:
```
./ibm-concert-std/bin/status
```

Copy data and configuration files to another directory for a backup:

mkdir <backup directory>

cp -rp  ./ibm-concert-std/localstorage <backup directory>/.

cp  -p  ./ibm-concert-std/etc/local_config.env <backup directory>/.

Expand the new ibm-concert-std.tgz package in the same directory that contains your existing installation of Concert, and with at least 512 GB of available disk space.
```
tar xfz ibm-concert-std.tgz
```
Edit the file ./ibm-concert-std/etc/local_config.env and remove the line that starts with "ROJA_IMAGE_TAG=".

Run a Docker or Podman log in to authenticate with the source image registry:

${DOCKER_EXE} login ${CONCERT_REGISTRY} --username=${CONCERT_REGISTRY_USER} --password=${CONCERT_REGISTRY_PASSWORD}

Run the following command to start your upgraded version of Concert:
```
./ibm-concert-std/bin/start
```
Confirm that the Concert services are running:
```
ibm-concert-std/bin/status
```
