This scenario may arise during a migration of LAE to Data360 Analyze.
When LAE runs locally, it occupies port 7721 by default.
To ensure that a new installation of Data360 Analyze does not conflict with a pre-existing installation of LAE, start LAE prior to initiating the Data360 Analyze installation.
When the Data360 Analyze installation detects an actively running instance of LAE, you will be prompted to manually specify an alternate port. This will automatically ensure that LAE and Data360 Analyze will not occupy the same port.
