We are about to upgrade our 6.1.2 to 7.1.3 but need to upgrade first to 6.1.3 then 7.1.3. as per previous blogs, also we have also upgraded our system over time from the initial I think 6.0 - before I joined. the question I have -
- Is there any benefit and can it be done to reinstall a clean Version as close to our 7.1.3 as possible so in the event we need to re-install from a single ISO source opposed to use the original source 6.0 and then upgrade various times ?
- What about the Database- If we need to rebuild using the newer single ISO 7.x.x can we do a DRS based current 6.1.2 or does Cisco need to be involved?
Example when we had to re-install our lab we had to install 6.0 and then upgrade several times to the current version, in production I would rather try to reduce the upgrades in the event of a major outage
When you sat an "installable 7.1.3b" , are you saying this is a new install as such so in the event we have to rebuild we can just rebuild using this DVD instead of going through the upgrade steps from 6 to 7.1.3.
If you have installable media, then it would be a new install at whatever point in the future that you needed to rebuild a node and do a DRS restore. You can use the installable media for upgrading you current install in-place as well. There is no need to do a fresh install at this time to get upgraded to 7.1.3.
The only reason we have this distinction between bootable/installable (physical media) and upgrade-only (available for download) is that Cisco tracks the royalties they have to pay through how many DVDs they ship physically. The contents are virtually the same but since the downloads cannot spawn a new installation, Cisco can safely not pay royalties to RedHat and all other underpinning vendors for every download.
