I believe so. ie in-place upgrade or clean build and importing data (exported using the R81.10 migration tool)
I'm gong to be preping for a MDSM upgrade from R80.30 to R81.10 shortly and my intention is to do the following:
- Export data from the MDSM using the latest R81.10 migration tool
- Build a new MDSM with latest Jumbo, CPUse Agent and migration tool (LAB)
- Import the data into the MDSM, ensure there are no issue that can observed.
- Once happy, arrange a maintenance window, snapshot / export database of the MDSM and store offline.
- Ensure all the OS level config is noted (export the gaia config).
- Conduct a clean build of the MSDM using a USB.
- Install Latest CPUse Agent, Jumbo and migration tool (same used for export).
- Import the data
