How to edit active model in Alfresco? I know, my aspects will be changed during the life of repository, and when I go into model manager, I wanto edit some data, for example type of data, I can't do it without deactivating a model. And I can't deactivate the model, when it is in use (so if any file has aspects from this model). I can't also remove all aspects from all files, because I will lose some important metadata. What can I do in that situation? I know, it has to be some solution, because I don't believe, that Alfresco doesn't allow to make changes in such important to change things like that. I did't find any solution so far.
