Hi folks,
I need to perform an Upgrade via ISSU from 11.4R9.4 / 11.4R10.3 to 12.1X46-D65.
As far as I can tell a direct ISSU will work without intermediate Versions, correct?
I found the following "nice to know" Note:
A problem is known in SRX 240 B2 and H2 model numbers if you are upgrading to 11.4R10 or higher JunOS version from 11.4R7/R8/R9. The Update will fail with the error "Please install a package with version 11.4R5 or Higher
An upgrade from Junos Release 11.4R7/R8/R9 to Junos Releases 12.1X45, and 12.1X46 is not affected by this issue and will work as expected.
Has anyone ever done an upgrade from 11.4 to 12.1X46 via ISSU?
