Error when upgrading from 1.7 to 2.0

Hi, I'm having difficulty upgrading from 1.7 to 2.0 following these instructions. I've copied in the 2.0 files, overwriting the 1.7 ones, and after updating setup.php and working through a couple other errors, saw this message when navigating to the front end:

There are issues with your configuration
General installation instructions can be found here. or more specific information on detected issues review the messages below:
You appear to be upgrading a CollectiveAccess 1.7.x system. Upgrading is a multi-step process. Learn more about it at here.

At that point, I attempted to run the caUtils update-from-1-7 call per the instructions to migrate the DB. However, when attempting to run the script i get the following error:

PHP Fatal error: Cannot declare class Configuration, because the name is already in use in /data/providence/app/lib/core/Configuration.php on line 54

At this point, I realized that the copy of the 2.0 files into the file system had not deleted or replaced two legacy folders in app/lib -- the folders /core and /ca respectively. This I assumed was my problem, so I removed the two folders, and the attempted to run the caUtils again, but now am receiving the following error (indicating that at least some of the classes from the legacy app/lib/core/ dir are needed:

PHP Fatal error: Uncaught Error: Failed opening required '/data/providence/app/lib/core/Logging/Eventlog.php' (include_path='/data/providence/app/lib:/data/providence/app/models:/data/providence/vendor/pear/pear_exception:/data/providence/vendor/pear/file_marc:/data/providence/vendor/pear/console_getopt:/data/providence/vendor/pear/pear-core-minimal/src:/data/providence/vendor/magento/zendframework1/library:/data/providence/vendor/pear/archive_tar:.:/usr/share/php') in /data/providence/app/plugins/ns11mmServices/ns11mmServicesPlugin.php:29

Can you advise?

Ah,
looks like there were a number of things in app/plugins/ that did not get removed either and those were causing some issues. Once I removed the legacy plugin dirs, caUtils script is running fine.

Judging from the errors you received those are very very old plugins. If you do end up needing them they will have to be updated for sure.

To ensure a clean upgrade you are better to put the new files into a completely new directory next to the old one, then move over any of your local configs, print templates, media, etc and setup.php. Make a copy of your database, update web server settings to point to new location and then run update/migration steps.
This ensures you can switch back to the previous version effortlessly if things go wrong, or continue to have a working site while you problem solve.
Once you’re happy everything is working correctly, then the old source code and database can be removed.

Thanks for the suggestions! I will for sure do that when working on our production instance (working through our staging one now to ensure this is a viable path.
