now we are going to deploy a new version from our applications, to avoid any risk we planed to design a roll back plan , so please anyone have an idea about how we can roll back the old version from application on IBM WebSphere application server , please i need it ASAP .
If you haven't yet deployed the new version, you can export a copy of the existing application as an EAR file through the WAS console (which you can then use as a backup to deploy if there are problems with the new version). In WAS 6.1, the process looks like this:
Applications > Enterprise Applications > Select the relevant application > Export.
