Hi,
You can find the current product catalog on the Meraki site under Resources > Product Catalog
https://meraki.cisco.com/product-catalog/
There is extensive documentation that includes End-of-Sale and End-of-Support information on the Meraki Site under Resources > Documentation
https://documentation.meraki.com/
For example if you search EOL in the documentation you will get helpful search results such as the following:
https://documentation.meraki.com/General_Administration/Other_Topics/Meraki_End-of-Life_(EOL)_Produc...
If you click on one of the products in this list you will be directed to a new pdf document explaining the various dates/models of Meraki equipment that has gone End-of-sale/support, what day they go End-of-Sale/Support and what the direct replacement would be if any.
For example the recent MR product update and its most recent products.
If you need any more information or clarification let me know I would be happy to help!
