If you already have Gramps installed, and you are only making a 'point' upgrade (i.e. from Gramps x.y.z to x.y.z+1, e.g. from 3.4.3 to 3.4.4), then it is likely but not certain that Gramps will continue to work. However, if the change is much greater, especially if it is a major version change (e.g. from 2.y.z to 3.y.z), then the danger that it does not work properly is much greater.}}
