Most Aida systems in production currently are 'image as database" based
and must therefore be carefully upgraded to new Aida versions, which is
usually done live, without shutting down. That's why we have quite few
years of experience migrating them without damaging or even loosing
production images. Stability of Aida web systems is therefore guaranteed.

Forthcoming release of Aida 6.0 will need a small migration of existing
classes, for which the necessary scripts are already prepared and also
tested on production systems. I namely update those systems with interim
development versions as well, to test enhancements in reality. So you
can expect a final release as already very stable one.

Short answer: following the migration notes you won't have problems
migrating from 5.6 to 6.0.
