Best practice: upgrading from NOS 1.1 to 1.2 without downtime

We're on 1.1.7 LTS with a single X5 (no failover partner). Docs recommend the cluster-aware installer but that assumes >1 node. Question: has anyone done the in-place upgrade to 1.2 on a lone X5, and if so how long was the control-plane blip? The data plane keeps forwarding I believe, but our billing runs against the control plane every 15 min and I want to make sure I schedule around it.

Did the exact same move last month (single X5, 1.1.7 → 1.2.0). Control-plane blip was 4 minutes total — 90 seconds for the actual restart, the rest for the AI engine to re-warm its indices. Data plane never blinked. Billing job at 15-min cadence had one skipped tick that self-recovered on the next run.

Ran the upgrade last night per this thread. 3 minutes 40 seconds blip, exactly as promised. Thank you for the confidence.
