Below are the snapmirror details for my volume. We are snapmirror going to a different filer for this volume and that is the only reason I enabled the snapshots. We need the snapshots since we already have the data at othere volumes, this is just a staging area. My question can I delete these snapshots and if yes which ones should I delete first?

Hello Thanks for the input.
This is just a temp staging volume and does not relly need to have snapshots so i deleted snapshots to free up the space. My concern was If i delete all snapshots will I be able to snapmirro the volume to a different filers
Here is the snap list for my destination SM volume. Which one is the baseline SM? Interestingly all %used and %total are 0%. I did an update to SM after baseline SM completed. the sourec volume is unexported so the user would not change data is it 0% because there is no change in source data? filer1 is the destination filer.

Your snapmirror relation is already gone. You can check it from either source or destination (it will also give lag time) using the command: snapmirror status
You can delete any number of snapshots now on source if you do not need any data from previous snapshots for recovery.
If you want to establish SM again, you must initialize it (start the sync again from beginning).
Please read some documents on snapmirror before working on it.
