• reuse up-to-date mautrix_whatsapp_ynh package (cool! it's already packaging v2)
• Find out what happens with existing portals after upgrade if signald was used as a primary device (primary device login in mautrix_whatsapp is not supported anymore)

What happens with existing portal rooms after v5 migration if my primary device was signald ?

Just keep your database, your portals will probably have a bunch of events sent to them, but they should continue to function
And keep your config.yaml to make sure you get the same mxid templates etc
