Upgrading via the Virtualmin UI
When a new version is available, you will see a message on the System Information page stating that there are Virtualmin package updates available.
Other packages may be listed too, depending on what is available to be updated. To install these updates, just click the Install All Updates Now button.
Upgrading from the command line
Installing all available updates can be done with the following command on RHEL/CentOS:
yum update
Or, on Debian/Ubuntu:
apt-get update
apt-get upgrade
Alternately, you can install specific packages from the command line as the 'root' user using APT or YUM. On CentOS or Redhat Enterprise, the command to use will be like:
yum install wbm-virtual-server bind perl python
On Debian or Ubuntu, you could use :
apt-get install webmin-virtual-server bind perl python
License Upgrades
When upgrading Virtualmin Professional licenses, it is never necessary to re-install Virtualmin!
