WP DB Error: [1146] Table 'DBNAME.site' doesn't exist SQL: SHOW COLUMNS FROM site

[dudzislaw]

I want to migrate from Matomo instance for WordPress to my own Matomo installation. The following error occurs:

php71-cli wp-content/plugins/matomo/app/console migration:measurable --source-idsite=1 --target-db-host=HOST --target-db-username=USERNAME --target-db-password=PASSWORD --target-db-name=DBNAME
Are you sure you want to migrate the data for idSite 1. (y/N)y

WP DB Error: [1146] Table 'DBNAME.site' doesn't exist SQL: SHOW COLUMNS FROM site

I see the problem in tablenames. It should be "DBNAME.WordPress-prefix_matomo_site" (there is such table in DB), but there is just: DBNAME.site.

I wonder if you could help me with this strange bug(?).

@dudzislaw you likely need to set the parameter --target-db-prefix=matomo_ for example. It's probably about the target DB where it fails and not the source.
