[Resuelto] Getting the Migration Code from original site's admin area, but admin area link redirects to new si...

Background of the issue:
I have migrated my site from a dev environment to a live site. WPML has notified me that I need to start a migration to ensure all WPML services continue to work. To do this, I need to copy the migration code from the original site's admin area. However, the original site's URL has been redirected to the new site's URL, making it inaccessible.

Symptoms:
The admin area link for the original site redirects to the new site's admin area, preventing access to the original site to obtain the migration code.

Questions:
How can I access the original site's admin area to get the migration code?
Are there any solutions if the original admin area is no longer accessible?
