I recomend thoroughly you open a case prior to do the upgrade, if not for the complexity about update procedure, but because support personel could help you uploading in the FTP for the case all software you need.
Indeed, URL fails in some zones, I don´t know why but when I did the upgrade I face with the same problem.
Maybe - If support don´t answer you - I can share this file with you somehow.
Hi, Jose, apologies for the delayed response, we managed to miss your note. Page 2 says this: "To upgrade the OEL operating system, your ESM version must be at least v5.0 GA". Does that answer your question?
When I´m upgrading OS on this appliances if I have not any ESM installed, What is the minor version accepted in order to be installed as a new instalation?
