Grafana Migration from 7.4.3 to Grafana 10

I am trying to upgrade grafana 7.4.3 to latest grafana version. It is getting failed while migration
It is first giving info logs as
msg=“Executing migration” id=“move dashboard alerts to unified alerting”
after it is failing

level=error msg=“Executing migration failed” id=“move dashboard alerts to unified alerting” error=“time: invalid duration "$min_interval"”
level=error msg=“Exec failed” error=“time: invalid duration "$min_interval"” sql=“code migration”
Error: ✗ migration failed (id = move dashboard alerts to unified alerting): time: invalid duration “$min_interval”

Is it possible to upgrade the version with alerts or is there any we can upgrade this.
