We know how excited you are to upgrade to SynetoOS 4, but before that, we kindly ask you to give some attention to the following:

You need to make sure that before starting the upgrade:

  • you planned the upgrade by scheduling it outside working hours or on a planned downtime;
  • you send us the Serial Numbers of the appliances and if it possible the ESXi version through an email confirmation at;

  • your firewall or proxy/transparent proxy is disabled and Syneto appliance has full internet access;

  • all virtual machines are powered off beside SynetoOS VM;
  • you have read the Upgrade Manual (attached below);
  • you have created a Syneto Central account using end-user credentials.

Small but important notes:

  • the upgrade must be started with the Primary appliance;
  • at the end of the upgrade process, SynetoOS reboot will be required;
  • upgrade duration estimated for 2 hours (primary and DR);
