what will happen to all my settings and changes I have applied in Studio to fusion weblayout when I install the next release of MapGuide/AIMS? Will I loose any of those? Or all settings saved in the repository?
I haven't yet started but before I do I would like to know what to expect when I do an update.
With programming I assume all changes are lost if changes are made in existing files but should still be around when I create new files. Is that correct?
What are your experiences with frequent new product releases? Is the update process painless? Does it depend on how much you have configured your weblayout?
Your data/layers/maps/settings will stay as they were, untouched in the repository until you write/modify/delete them with Studio or the MapGuide API.
Each version of MapGuide/AIMS installs to their own folder anyway, with their own separate repository, so it's not as though your applications and data will be trampled over by a new MapGuide/AIMS installation
Same thing applies to any code you've written. But really, you should be using source control (svn/git/etc) for your code, like any professional software developer should, so this is a moot point.
MapGuide/AIMS upgrades generally follow this pattern:
1. Package/Backup current data and applications
2. Uninstall/Disable old release
3. Install new release
4. Restore data and applications to new installation
It's very hard to trash your data and applications in a way that is not of your own doing.
