Kentico 9 Upgrade

Jon Tibbetts asked on February 25, 2016 15:26

We looking to upgrade our site to the latest version of Kentico 9.

Currently we are at version 8.1.6

Is there any major concerns when upgrading to 9. Or is it the standard upgrade of upgrading the database to the newest schema format. And then making sure our custom code works with the new API.

If there is any gotcha’s please advise. Also we are looking to get on a semi normal upgrade schedule. Do you recommend upgrading with each major release or half releases etc. Also do you have an estimate of how long developers spend on hours doing upgrades to their websites.

I went from 7 to 8.0 to 8.1 to 8.2 to 9 and it took me a total of 5 hours (and there was some custom coding).

As long as you make sure to load the site (so the scripts that run at load actually run) between your hotfixes, it was very easy! Especially from the version 8's to 9.

Version 9 has very little API changes from 8, so just check your coding.

Usually you hotfix if there are security issues or a bug appears that a hotfix has fixed. But that is something your company needs to establish, the hotfixing tool makes hotfixes very easy, just what your customer is willing to pay for maintenance.

How much time upgrading will most likely depend on how much customization has been done, and how the they were done.

thanks for the info guys

I attempted the 8.1.6 to 8.2 upgrade and everything seems fine but now I only see the header after login in the admin area. None of the modules show up in the bottom. Am I missing something?

Nevermind I was able to answer mine own question, I needed to clear my browser cache to the beginning of time not just the last day or so....
