In the past, upgrading to the next release has been a sore spot for users of Linux Mint. The main release (based on Ubuntu) ironed out this difficulty with Mint 17 LTS (Long-Term Support).
Linux Mint Debian Edition is, as the name indicates, based on Debian and has only had 2 releases. Previously, LMDE 2 "Betsy" suffered from the no-in-place-upgrade problem. Chief developer at Mint, Clement Lefebvre, has written a tutorial describing how you can now update from LMDE 1.
As Silviu Stahie notes at Softpedia
Don't hesitate to connect to the IRC while performing the upgrade. One important note among the warnings: Make sure to disable Romeo prior to upgrading. Cinnamon 2.6 and MATE 1.10 will hit it very soon [but] they're not fully stable yet. If you want to test them, it's better to enable Romeo post-upgrade so they don't interfere with the upgrade.
