Hi,
Thanks for response,
Ypu said that 12.3 code releases has been extended until [at least] June 30 2017 now is 28-Sep-2017 and if iam look at this: http://www.juniper.net/support/eol/junos.html#1
I can see that 12.3X54 extend till 18-Jul-2018 is it the same as 12.3 ?
I didnt understand "Reason is that none of 13.X or 14.X really applied to legacy EX products", you saing that Ex3300 dont have 14.1 version ?
Do you know what are the upgrade path for Ex4550 from 12.3R7.7 to 15.1R5.5 and why ?
The reason for upgarde is old version and want to run the recomanded version.
Regards
