My current installed TrendMiner version is 2022.R2.0 or higher.

In case you are running on version 2022.R1.0 or older, please upgrade first to version 2022.R2.0.

I have VM console access.

In case issues occur during an upgrade TrendMiner support might request console access to efficiently resolve these issues. In case console access is restricted by the company it is advised to prepare for a temporary access permission for efficient troubleshooting.

I have a recent VM snapshot.

Taking a VM snapshot before an upgrade is considered mandatory. Read here why.

I have a recent database backup.

Read here why this is important and check here how to take a backup before an upgrade.

I have enough free disk space.

The available free disk space should be 25GB + the size of a TrendMiner backup if "Take backup before upgrade" is enabled. In case of doubt we advise to create a backup manually, check the free disk space when the backup is completed and trigger the upgrade with the option "Take backup before upgrade" disabled.

I have updated the CentOS 7 default repository references.

If you are using CentOS 7, you will have to update the default repository references. The following commands have to be executed as the root user:

sed -i 's/^mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*.repo
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*.repo

My system meets the minimum system requirements as listed below.

All connectors are running on a Windows server with Microsoft .NET 4.8 or higher installed.

As of connector version v4.13.0 the required .NET version is 4.8, compared to .NET 4.5.2 for previous releases.
