The migration plan
Roughly 15 weeks for a mid-size estate, in six phases.
Tooling & automation
Stand up vLLM/TGI on GPUs (or managed inference); front it with an OpenAI-compatible gateway; migrate prompts and eval suites; A/B against the incumbent; cut over by workload.
OffVendor's wizard pre-fills these scripts with your environment — inventory export, disk/schema conversion, bulk provisioning, and validation.
