Upgrade checklist
For the Enswitch owner: - Have you reviewed all the Enswitch functional changes and planned for each of them? - Is the Linux distribution package manager working on all servers? Please test it in advance. - Will one of your engineers be available during the upgrade in case of problems, and afterwards to test Enswitch is working? - Can any CDRs be deleted in advance to speed up the upgrade process?
For the upgrade engineer: - Is firewall, ssh, and sudo access working on all servers?
