Hi,
Ok i understand the reason why not upgarde, but i still have some questions
1. If 21.3 is the most standing version why juniper recomanded version is 15.1 ?
2. Can you explain (in details) me why you are saying that i can upgrade direct from 12.3 to 15.1 ? ( i tried to understand juniper upgrade rule with no success),
12.3 is EEOL and 15.1 is not, (or maybe 15.1 is also EEOL ?)
3. I tried to upgrade Ex3300 vc*2 from 12.3R6.6 to 14.1X53-D45.3, and it was hard, i know that there is big diffrence on L2 component betwwen the versions, finally I had to intervene and connect with consol to the vc, they say that we can not upgrade non EEOL with more then 3 realse, what do they mean by realse, 12.3. to 14.1 is one realse (since 13 is no longer available ) ? realse is before the dot X.1 or after12.X ?
The upgrade peoccess was:
request system software add member 0 /var/tmp/jinstall-ex-3300-14.1X53-D45.3-domestic-signed.tgz validate
request system software add member 1 /var/tmp/jinstall-ex-3300-14.1X53-D45.3-domestic-signed.tgz validate
And after that: request system reboot
Regards
