New host > migrate Woo site

Hi so we have begun steps to migrate a woocommerce site from one hosting provider to another.
We have successfully cloned the site content to the new host using ManageWP as a test but want to avoid future bumps in the road.

Using the ‘Retro’ theme by Olegnax.
After the site was cloned to the new host, on the new host we completed the Woo updates to the latest major version(Olegnax only recently updated the theme to support the new Woo)

We also obviously need to activate the woo plugins we purchased(Subscriptions, Memberships, plus others)

All seems to be OK so far but we have encountered the following messages at the top of the screen when logged into the WordPress backend:
shipping_canada_post::calculate_shipping($package) should be compatible with WC_Shipping_Method::calculate_shipping($package = Array) in /home/thelaundrytarts/public_html/wp-content/plugins/canada-post-woocommerce-shipping/includes/class-wf-shipping-canada-post.php on line 1346
