web.log

[https-####-##-127.0.0.1-8443-exec-9, Ent: HybridityAdmin, , TxId: TxId: ######-######-######-######] ERROR c.v.v.h.a.m.MobilityGroupRestController- Error while validating Mobility Group request.
java.lang.RuntimeException: Failed do to do migration quick validation null.

Environment

HCX 4.11

Cause

This was caused by the validation process attempting to read the destination network ID from the stretched network list, where it encountered stale network extension entries missing source and destination network details.

Resolution

Kindly raise a new Case to involve Broadcom Support to address this issue as DB modification is required to remove stale entries.
