How big a jump is safe?

We have been running 0.20.3 in fully distributed mode for almost a year now, and we are going to upgrade.  How big a jump is safe, and would best practice going to 0.9x.y be to export, upgrade, format, import?

Thanks

Greg

It's safe, all the big installs I know are either on some heavily
patched 0.89 or a late version of 0.90.

You might want to do an export before upgrading, or a complete HDFS
distcp, just for good measure.

Also read this guide from the online book:
