Update Junos version in SRX cluster

Hi Guys,

I need to update two SRX 220h in cluster, but when I tried to copy junos version from Node0 to Node1, the imagen was corrupted, I used the following command in start shell mode: 

rcp -T /var/tmp/junos-srxsme-12.3X48-D30.7-domestic.tgz node0:/var/tmp

I was reading about it, I mean the best practice but it was not possible,

Any maybe knows how I can do it?

Many thanks, 

Regards.

Model: srx220h2
JUNOS Software Release [12.1X45-D15.5]
