We are running Lotus Notes 4.55. Yes, still running this software that was only installed to be Y2K Compliant. We have one database on the server that is still in use in a somewhat critical function. the problem is that the main certificate that was built in 1999 is set to expire on April 29th, 2019. I can't determine what I need to do to make it so that Notes doesn't die on that date. Anybody have any suggestions on how to either re-cert our issuer, or something? There is almost zero documentation on this as I'm sure nobody actually thought somebody would run the software long enough for the cert to expire.
