SonicWall recommends a stepped upgrade process that goes from one major version to the next. For example, a system running 8.0 is incrementally upgraded going from version 8.0 to 8.1, then 8.1 to 8.5, 8.5 to 8.6, 8.6 to 9.0, and then it can be upgraded from 9.0 to 10.0. Skipping versions may work, but is not recommended. Skip versions at your own risk.
If you notice any issues please get in touch with SonicWall Technical Support.
Secure Mobile Access 10.0 firmware is only supported on SMA 200, 210, 400, and 410 appliances, SMA 500v for ESXi, and SMA 500v for Hyper-V. Version 10.0 is not available for SRA platforms.
