How to Verify config before loading to F5

Hello!

To avoid issues when migrating configs, don’t load an edited UCS file directly onto new F5 hardware. Instead, extract and inspect the UCS, use tmsh load sys ucs verify to catch syntax errors, and manually rebuild base networking (management IPs, self‑IPs, HA VLANs) on the new devices. Then merge only the application objects (virtual servers, pools, profiles) using tmsh load sys config merge. This prevents inoperative states and ensures HA/Sync‑Failover stability. Establishing iQuery after the config load is fine, but only once GTM/DNS sync groups are properly set up.
