Installation and Upgrade Considerations
ECS Appliance and Software installations and upgrades must be performed by Dell personnel. For more information about how
to schedule an installation or upgrade, contact Dell Support.
When installing or upgrading, the preferred method of connecting to ECS is remotely through Secure Remote Services. Remote
upgrades can be performed using WebEx sessions. For sites with no outside connection, upgrades must be scheduled with Dell
Support to come onsite.
For more information about the upgrade process, see the ObjectScale/ECS Upgrade Guide.
