You can upgrade to Workspace ONE Access 20.10 directly from either Workspace ONE Access 20.01 or VMware Identity Manager 19.03 on Linux.
Starting with version 20.01, the VMware Workspace ONE® Access™ service (formerly known as VMware Identity Manager™) is available on-premises solely on Linux. If your existing Linux deployment is a version earlier than 19.03, you must upgrade to 19.03 first.
To upgrade VMware Identity Manager 19.03 on Windows to Workspace ONE Access 20.10, do not perform the upgrade procedure. Perform the migration procedure from VMware Identity Manager 19.03 on Windows to version 20.01 on Linux first. See Migrating Windows to Linux for VMware Workspace ONE Access 20.01.
For existing Linux deployments, if you prefer a fresh installation to an upgrade, see Installing and Configuring VMware Workspace ONE Access. Remember that a new installation does not preserve your existing configurations.
This information is intended for administrators of Workspace ONE Access. The information is written for experienced Linux and Windows system administrators who are familiar with VMware technologies, particularly vCenter™, ESX™, and vSphere®, networking concepts, Active Directory servers, databases, backup and restore procedures, Simple Mail Transfer Protocol (SMTP), and NTP servers. Knowledge of other technologies, such as VMware ThinApp®, Citrix-published resources, and RSA SecurID, is helpful if you plan to implement those features.
Workspace ONE Access and Other Technologies
You must integrate the Workspace ONE Access service with several other technologies, including the Workspace ONE Access connector, which starting with version 19.03, is available solely on Windows. You must integrate the service with other VMware technologies, such as vCenter™, ESX™, and vSphere®. Knowledge of many other technologies is required, such as of Active Directory, databases, backup and restore procedures, Simple Mail Transfer Protocol (SMTP), and NTP servers. Knowledge of other technologies, such as VMware Horizon and RSA SecurID, is helpful if you plan to implement those features.
