Mender 2.4.0 to 2.6.0 upgrade loses devices

[mterwoord]

I went ahead this weekend to update our 2.4.0 mender server to 2.6.0.

All seemed to have worked well, except that, out of the 60+ devices, only 10-15 show up after the upgrade.
Is there something that needs refreshing? Am I missing steps in the documentation?

Any help is greatly appreciated!

With kind regards,

I should have done some more googling.

Following post contains some exta steps that might be needed when going from 2.4 to 2.5. It also fixes my problems:

Mender 2.5.0 Problems with Filters, Hostnames and More

Hi @ckelloug2, thanks for using Mender and I’m sorry to hear 2.5.0 is causing issues for you. Can you please try entering the deviceauth container, e.g. running: $ docker exec -it <name of your deviceauth container> sh Then, from the container, you can run: $ deviceauth propagate-inventory $ deviceauth propagate-inventory-statuses $ deviceauth propagate-inventory-id-data This will sync all inventory, statuses and identity_data attributes from deviceauth to inventory. Please let us know if…

@mterwoord correct, upgrading from 2.4 to any later version requires a full resync of the deviceauth and inventory services.
