Virtuemart 5 and Joomla 6 migration

[alxgan]

Hello,

I will like to migrate both Joomla 5.4.9 with Virtuemart 4.6.8 to Joomla 6 and Virtuemart 5.
Is there an order to this?
Should I just update Virtuemart with com_virtuemart.4.9.3.11254_package_or_extract.zip and after that update Joomla? Or first Joomla and then Virtuemart?!
Any good advises with this process?

Thank you
