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 support@syneto.eu;

• 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);
