Is there any reason to keep the old data around now? If it's not used by anything I'll free some space up.
I could think of a couple reasons, but they may not apply to you ...
- one day we might want a low res/light weight scenery set
We could still build that from the higher-resolution set by sampling.
- SRTM data doesn't cover the entire earth ... They never flew past +/- 6x degrees latitude (where x is a number I don't recall ... greater than 0 but less than 9.)
- SRTM isn't released yet for australia.
Here are the details:

These are good reasons, but they suggest keeping around the older DEM stuff only where SRTM isn't available.
All the best,
David
