We recommend that you use Junos OS Release 15.1X49-D172 in your production environment instead of Junos OS Release 19.3R2-S2 because of the following known limitations in Junos OS Release 19.3R2-S2:

Note

The issue related to ZTP not progressing in an SRX3xx dual CPE cluster, if secure OAM tunnel from the master node is down is resolved in Junos OS Release 19.3R2-S2.
