Upgrade from 1.1.x to 2.0.0

MyEnv 2.0.0 requires an new PHP package for socket handling. On Red Hat, CentOS, Debian and Ubuntu it seems to be installed by default. On OpenSUSE it has to be installed (php-sockets). For more details see also our MyEnv Installation Guide.

shell> sudo zypper install php-sockets   # on OpenSUSE and SLES only

shell> cd ${HOME}/product
shell> tar xf /download/myenv-2.0.0.tar.gz
shell> rm -f myenv
shell> ln -s myenv-2.0.0 myenv


If you are using plugins for showMyEnvStatus create all the links in the new directory structure:

shell> cd ${HOME}/product/myenv
shell> ln -s ../../utl/oem_agent.php plg/showMyEnvStatus/

Upgrade of the instance directory structure

From MyEnv v1 to v2 the directory structure of instances has fundamentally changed. Nevertheless MyEnv v2 works fine with MyEnv v1 directory structures.

Old structure


New structure


But over time you possibly want to migrate the old structure to the new one. The following steps describe how you upgrade MyEnv instance structure v1 to v2:
