I tried to move my data from a manual installation to NCP. However, this failed. This could be because the version number differed a little bit and I also had an sqlite database which is not supported out oft he box with NCP.
Then, I decided it is cleaner to export all my data from the old instance and import it to the new one. I use files, calendar and contacts. I exported them via the web interface. Is this a good idea? Will all kind of metadata be exported and imported again for calendar and contacts or is there a better way? Is there anything else I should remember when manually migrating data to a new instance?
