Given recent restructuring involving VMware, improvements in Hyper-V and emergence of new and reliable Hypervisors such as Proxmox, this seems to be the year of migrating to a new Hypervisor platform (or planning to). We've been working with Hypervisors since the beginning, and in fact helped with the first security benchmarks at both VMware (corporate documentation) and at Center for Internet Security.
With multiple migrations over the years, we're experts in minimizing downtime and anticipating issues during migrations. It doesn't matter if your migration involves on premise hypervisors, colocation facilties or migrations to Azure, we've been there.
Changing Hypervisors doesn't have to involve production outages!
Similarly, we've done hundreds of switch, firewall, router and wireless migrations over the years. Defining the migration approach to minimize outages and prevent post-migration issues are always the two main goals.
If you need your platform migration to NOT be a bump in the road, we can help with that.
