I have been working under an organization's salesforce instance for a little under a year now and have created custom objects, API endpoints, LWCs, and more.
There has now been a a structural change where there will be two organization salesforce instances and all of my work needs to be transferred to that new organization.
Just to note, I am NOT talking about using change sets to transfer changes between one Salesforce instance to another with the same organization. I am talking about transferring changes between one organization's salesforce instance to another organization's salesforce instance.
I know that this is not possible through change sets. From some research, I've found something called the ANT Migration Tool, but it states that it's a utility for moving meta data from a local repository to a salesforce org, and I'm not sure how you would get your work down into a local repository.
I do use VSCode's SFDX Extension for my work, but when I authorized with my organization, did that pull down all the meta data? Can I just authorize my SFDX project with another org and upload to that org?
