The minimum Controller size supported from 30.2.1 is 6 vCPU, 32 G RAM (Small).
All Controller nodes in a cluster must be homogeneous in terms of memory, CPU, and disk configurations.
Ensure compliance with enforced system limits in version 30.2.1. Exceeding the enforced limits will block upgrades.
Requirements to Upgrade Controller Clusters:
All Controller nodes in a cluster need to be in the same software base and patch versions.
All Controller nodes in a cluster must meet a minimum requirement of 6 cores and 32 GB of memory. Due to this requirement, Controllers which are in the Essentials sizing cannot be launched.
Controllers will fail to upgrade if they are in the Essentials flavor (less than 6 cores or 32 GB of memory).
If FIPS mode is enforced, all Controller nodes in a cluster must also be FIPS-enabled.
