It seems like every time I do a migration with the WordPress importer, something about my data breaks. For instance, while writing my Year in Review post just now, I noticed last year’s post has an incorrect image:
The image should be the visualization.
It would be really neat if I could verify a migration with WP-CLI. Using the WXR file as the baseline, the command would iterate through all of the data in the file, compare it to what’s present in WordPress, and alert me if anything is missing or unexpectedly different.
