Picklists and associated comments with the removal of samples in that picklist, should be able to be exported and imported into new Freezerpro instances.
Current freezerpro versions picklists can be exported but are not exported with with comments associated with the removal of samples. When importing samples, although the old instance has the sample removed, when importing samples into the new instance, the sample appears again like it is in the freezer without the removal date and comment associated with its removal.
New freezerpro versions should address this.
