Query SSIS packages details from file system

Hi All,

I have around 500 packages (SQL 2005) deployed in file system & all this packages are running on daily basis via SQL agent. Now I need to migrated all 500 packages into SQL server 2008 R2.

There is no inventory to track which package belogs to which team and any other information.

Now, I need a method to query the pakages connection string details with database respective. Is there any method?

Thanks
