## AI overview

The article discusses migrating a data center fabric from traditional VLANs to VXLAN. It recommends building a parallel fabric and connecting it to the existing one, while explaining the hardware, link-speed, capacity, and migration-service constraints of incremental upgrades.

## Source excerpt

Darko Petrovic made an excellent remark on one of my LinkedIn posts: The majority of the networks running now in the Enterprise are on traditional VLANs, and the migration paths are limited. Really limited. How will a business transition from traditional to whatever is next? The only sane choice I found so far in the data center environment (and I know it has been embraced by many organizations facing that conundrum) is to build a parallel fabric (preferably when the organization is doing a server refresh) and connect the new fabric with the old one with a layer-3 link (in the ideal world) or an MLAG link bundle.
