URL change - Sitemap update / redirect

[bgvsiteadmin]

Hi everyone

Recently we performed a massive, hybrid site migration (CMS, URL, site structure change) without losing any traffic (yay!). Today I am finding out that our developers+copy writers decided to change Some URLs (pages are the same) without notifying anyone (I'm not going into details why). Anyhow, some URLs in site map changed, so old URLs don't exist anymore.

Here is the example:

• OLD (in sitemap, indexed): https://www.domain.com/destinations/massachusetts/dennis-port
• NEW: https://www.domain.com/destinations/massachusetts/cape-cod

Also, you should know that there is a number of redirects that happened in the past (whole site)

Example :

Last couple years redirections:

• HTTP to HTTPS
• non-www to www
• trailing slash to no trailing slash

Most recent (a month ago )

• Site Migration Redirects (URLs / site structure change)

So I could add new URLs to the sitemap and resubmit in GSC. My dilemma is what to do with old URL? So we already have a ton of redirects and adding another one is not something I'm in favor of because of redirect loops and issues that can affect our SEO efforts. I would suggest to change the original, most recent 301 redirects and point to the new URL ( pre-migration 301 redirect to newly created URL). The goal is not to send mixed signals to SEs and not to lose visibility.

Any advice? Please let me know if you need more clarification.

Thank you
