Map Uploader will try to match the local table with a server table. It does this by getting the tab file or database table name from MapInfo Pro and looking for a match in each connection on the server. If a different table name is used locally versus on the server then a match will not be found, or an incorrect match may be found. To fix this, change one of the table names. To easily move a copy of a MapInfo Pro project to another server, use the Workspace Packager tool to copy all the referenced data to a single folder.
