Sync between Creator & Reports

Sync between Creator & Reports

We use Creator extensively. W e now need to reduce our  record count which means  deleting older  records before a certain date. We need to keep these records somewhere though, so we are planning to export them to Reports. 

The power of Reports in  visualizing/manipulating data  looks fantastic, so I am  wondering whether I could use  Reports to sync with Creator ( as I've seen is possible) so  that we have all sales data,  both older and recent, in  Reports to manipulate/ visualize. 

However, I still need to  delete the older records in  Creator so that it frees up  more space. So, the questions  is: Is the "sync" a 2-way syn or 1-way syn? If I set up a scheduled  export from Creator to  Reports, can I then delete  older records in Creator and  will they still be present in  Reports after future syncs or will the "sync"  also delete them from Reports  when it finds they longer  exist in Creator?

Thanks for your assistance.
