We need to import POA application with more than 10MB. How can we do that? It seems that POA import wizard has a 10.8MB limitation for local files:
"size of uploaded file must be less than 10.8MB"
Large packets should be imported via a URL. You can put your package to some server that allows files to be downloaded via direct links and then import your package via URL.
Simplest solution - make use of Apache installed on your endpoint server. You have ssh access to all servers in your sandbox, root password is the same as initial one for 'admin' user in POA panel.
If you have an early dropbox account with 'Public' folder which allows direct downloads or any other service with similar functionality that will also work.
