Install the new Axon.ivy Engine version to a new installation directory (See section Install Axon.ivy Engine).
If necessary (according to the Migration Notes), request a new licence (see section Installing a Licence).
Back up the system database and the application file directories of the old installation.
Copy the file
serverconfig.xmlplus all YAML and properties files from the
configurationdirectory of the old installation directory to the
configurationdirectory of the new installation.
Unless a new licence is required you should also copy the old licence file to the new installation.
If you have modified any other configuration files located in the
webapps/ivy/META-INFdirectories of the old installation then apply the changes also in the corresponding files in the new installation, if required. To see what has been changed, we recommend the usage of some diff tool to compare the individual config files of old and new installation.
If you have installed additional extension plugins into the
dropinsdirectory then copy them to the
dropinsdirectory of the new installation directory if they are compatible with the new Axon.ivy Engine version. For those which are not compatible try to get new compatible versions and install them.
