[cisco-voip] CUCM Pre-Upgrade Checklist

[Ryan Huff]

It was the 1GB max per transaction file size, but was then fixed. I don’t think they’ve restricted their cipher suites either, so I think it still works with CBC-Blowfish and other older/weaker suites .... which is why folks like it on CUCM; might not be the most secure but it just works.

I vaguely recall something changing with FreeFTPd that specifically broke our DRS and that’s why it’s no longer supported.
i don’t know if it was a max file size or something else.

I just noticed Cisco now supports freeFTPd, but they stopped supporting my favorite SFTP product "free FTDP."  :(

Has anyone seen this lately?  This thing is nuts.  I've been doing upgrades for like 10 years now, and this seems a little over the top.

Some Highlights:

"If you have custom ringtones or background images in the TFTP directory, you need to create a separate backup for these files. They are not included in the Disaster Recovery System (DRS) backup file."

Good to know.  I must admit that I didn't know that.

"Record the following login and password information: all application users credentials, such as DRS, AXL, and accounts for other third-party integration"

What?  Why?  What do you plan on doing with my configuration?

"Record the settings for Enterprise Parameters on both [CM] nodes and [IM&P] nodes. [T]he settings that are configured on Unified Communications Manager nodes overwrite the settings configured on IM and Presence Service nodes during the upgrade process."

Well that's some lazy software engineering right there folks.

"Export user records using the Bulk Administration Tool (BAT)."

That's a nice list of users you got there.  It would be a shame if this upgrade deleted all of them.

And the list just goes on, and on, and on.  The pre-upgrade is as long as the upgrade.  Who legitimately is already doing 100% of these things?
