Harry is correct, EX4200 and EX4300 are not compatible to run in a VC together.
Just on lifecycle for those old switches ... EX4200 was end of sale Jan 2019, and goes End-of-service on 30 June 2024, in couple of weeks. EX4300 24/48{P/T] was end of sale Jun'22, with end of support 2029.

EX4100 & EX4400 are usual replacements folks consider for these, or EX4100-F if power redundancy is not needed.

Hi Muhammad,
I don't believe these can be used together in the same VC as they both run completely different versions of Junos and have different config between the 2 models.
Virtual chassis requires the same version of Junos to operate properly. Your options are to split your devices in to 2 different VCs one for 4300s and one for 4200s, or replace the rest of the VC so that they are all the same models.
Many thanks
Harry

Hi ,
We have ex4200 7switches, but primary switch get problem, therefore we have replaced with Ex4300, but now facing issues with whole network, all device getting disconnected, however 6 Ex4200 and 1 Ex4300(primary) are up in Virtual chassis.
Are we missing any configuration step?
Ex4200 and ex4300 are not compatible as primary and Backup?
