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.
