The LMDE Upgrade Tool in BETA is being offered to help users upgrade Linux Debian Edition 4 ‘Debbie’ To 5 ‘Elsie’. Earlier Linux Mint Debian Edition (LMDE) 5 was released last month, this made it possible for users to upgrade Linux Mint Debian Edition 4 ‘Debbie’ to 5 ‘Elise’.
While many users installed the LMDE 5 Elsie right away, others are still using the LMDE 4 ‘Debbie’, the previous version of the distribution.
If you also want to upgrade but have confusion or find it complex, the LMDE Upgrade Tool in BETA is available. You can use this tool to upgrade from Linux Debian Edition 4 ‘Debbie’ To 5 ‘Elsie’. You need to remember the tool does not work on “regular” Ubuntu-based Linux Mint.
The steps are simple and straightforward, follow the instructions here. A word of caution, being a BETA version and if you depend on your LMDE installation, you may need to be aware of a few bumps down the line.
As it is still being unfolded to its potential by the developers, it is labeled as BETA. There may be some bugs here and there that they will fix before releasing a stable version for the same.
You can always try the tool on a nonproduction machine, and wait for the stable version to arrive.
If you choose to go ahead and install and encounter any bugs, you can report them on GitHub.
