For those OS X users itching to get onto Lion, but FileMaker compatibility is holding you back, you have a dim green light. FileMaker just posted some details on FileMaker’s compatability.
Proceed with caution since there might some hidden ‘gotchas’ that haven’t come to light yet. But if you don’t use Web publishing, older excel exports (Pre-Excel 2007), Asian characters and 0 and negative decimal place, you might dip your toe in the water.
OS upgrades are serious business, especially with production systems, so we don’t recommend jumping in cold. Test on a development server and non-production clients first, and be sure and have a full backup of both your computer and custom FileMaker solution.
