The 9.8 upgrade

[martin_kane]

I notice that 9.7.1.0.30 is not listed in the official upgrade path for 9.8 - surely I don't have to downgrade to 9.7.0.0.220 before upgrading?

Always refer to Release Notes for official upgrade details. And from the 9.8 RN,
the official upgrade path is from one of these previous releases.

4.1.1. Official 9.8 upgrade paths supported:
• 9.5.3.0.45 (9.5 MR3)
• 9.6.0.0.267 (9.6 GA)
• 9.6.1.0.15 (9.6 MR1)
• 9.6.2.0.13 (9.6 MR2)
• 9.7.0.0.220 (9.7 GA)
• 9.8.0.0.112 (9.8 Beta)
• 9.8.0.0.203 (9.8 LCS)

Always save a backup configuration before upgrading, and it's recommended to
add the version digits to the filename to remind you what version it came from.
If you do need to downgrade, you can reload the previous configuration instead
of factory default.

The issues that have required ZD110s in Smart Redundancy to break SR and
upgrade individually have been resolved in 9.8.

9.8 GA release has been delayed by intense QA testing, and was supposed to
have been released earlier. Many important bug fixes were therefore added to
9.7.1 builds, both .17 and .30, due to need. Please upgrade from a QA upgrade
tested image, per the 9.8 Release Notes.

This is unfortunate, I would think 9.7.1.0.30 should be a supported path.

Based on the release notes it makes more sense to upgrade to 9.8 LCS and then 9.8 GA rather than downgrade to 9.7 GA, no?

I need to know how to downgrade from the current 9.8 back down to 9.7.0.0.220 so that I can try again, following the correct upgrade path. Maybe that's why my filtering of Generated DPSKs doesn't work? 🙂

What is the recommended path to upgrade to 9.8 from an already installed 9.7.1.0 build 17 ?

thanks.

I am in 9.7.1.0 build 17 version, and when I installed it I was not aware it was potentially a deadlock to upgrade.
