one issue.
the migration scripts don't take into account older load balancing configs.

if the test > rule > type > ping isn't explicitly set then the rule defaults to the next hop address and ignores the rule entirely.
the default rule seems to be the next hop address for the interface.

set default check type ping https://github.com/vyos/vyos-1x/pull/1998

This issue was tested in two version which are
1.4-rolling-202212080318
1.4-rolling-202209130217

Veth is not ready to work together with netns
As Interface moves entirely to logical stack and with the next commit will be recreated and try to move to netns again. As it doesn't see veth interface which moved to another logical stack, it tryes to recreate this interface.
We should either fix it or revert the previous commit.

@Viacheslav Thanks for the prompt response. Not sure if the change will also cover L2TP as well. For example:

set vpn l2tp remote-access authentication radius accounting-interim-interval '60'

Sometimes it stuck for ~1.5 minutes after deleting.

tcindex classifier is removed by upstream kernel, so

fails.
