Hi Cesar. one option would be to disable admin security temporarily, then use the admin console to import a new certificate, then enable admin security again.
How to disable security is documented here:
Disabling WebSphere administrative security when admin console is not accessible (ibm.com)BTW: I assume you are aware that WAS v7 is out of support since several years now. If you would like to move to a supported version of WAS, you should use the Binary Scanner to get an impression about the efforts.
