Install WindRiver replacement server
Open, HighPublic

Description

As Scaleway offers -20% for 36 months commitment, and as there are price drops on servers, we decided to switch to a PRO-4-L offer.

Other contenders was to keep a PRO-6-S or use a PRO-6-M, but S in't available and -M is only -8% for 12 months.

Plan is to install this new server and transfer data from relevant partitions with ZFS send/receive, then switch public IP address to this new machine.
