I am using conf7.3 version and I have one small issue. The issue is with yang compatibility with the old images.
Previously for a Yang CLI, we were using max-element value as 16. Now this max-element value changed to 64.
The issue is when we load the old image where max-element support was 16 we are getting below error on bootup. and because of that our confd service not getting started and console is blocked.
CDB: Upgrade failed: Upgrade transaction failed to validate: too many /gw-system:ip/nat/inside/source/static/tcp-udp-list, 64 configured, at most 16 must be configured
Can someone please help me how can I handle the downgrade gracefully or is there any way to handle this issue.
Why confd does not discard extra rules configured and send only 16 rules with old image.
