Is there a way to upgrade an existing raid array using metadata format
0.9 to a 1.x format without loosing data?

Not really. It is on my list of nice-to-have features for mdadm, but it is
not near the top.
As 1.x uses less space for metadata you could simply recreate the array as
--metadata=1.0
All the data would still be there.
You should be as explicit as possible in the --create command.
mdadm --create /dev/md0 --level=XX --raid-disks=YY --chunk=ZZ --size=QQ
--layout=LL --assume-clean --metadata=1.0
You can only convert to 1.0 metadata as 1.1 and 1.2 put the metadata on top
of where data currently is.
