Cause

The NSX-T migrator coordinator will create on single NSX-T Uplink profile and doesn't permit multiple LAGs in the same Uplink Teaming Profile, which leads to this error.

Resolution

Currently, there is no resolution.

Workaround:
A DVS LAG change is needed, reduce the number of lags on the DVS to 1.
