Merge whole two sentinel -1 datasets

Hi everbody

I would like to merge whole 2 sentinel-1 datasets? and merge tool does not work properly, I think two whole sentinel 1 datasets is too much for merge?
any suggestion

Thanks

AFAIK Sentinel-1 Merge works only between subswaths/bursts of the same product not inter-product. If you want to merge subswaths/bursts processed from two different products use other general tools like GDAL CLI applications.
