Application Development Software

Hi,
We need to migrate the content that is stored in development environment to test environment very often. But as the content is growing it is becoming really hard to migrate the complete content from one environment to another. As of now the size of archived content is around 1.5 GB. We have to FTP all that content over VPN and and then import that content back in test environment. This is taking lot of time.

Is there a way we could do incremental archive of content. Nature of content is WCM and involves mainly data files and some static file like PDFs. When we do incremental migration we want to migrate the metadata records of the new content along the with new versions of data files.

Regards,
Pratap
