This is a guide on how to create a new MIKE+ project in preparation for the migration of a MIKE 11 or MIKE HYDRO River model.
#01 - Create a new MIKE+ project
Launch MIKE+ and create a new MIKE+ project via File| New (Fig. 1).

The New Model Setup dialog appears (Fig. 2). Complete the information on the Model Selection tab with these key items:
- Model type: Choose ‘Rivers, collection system and overland flows’
- Unit system
- Database type: MIKE+ supports two database types: (1) Sqlite and (2) PostGIS. A Sqlite database is the default option, which suits most general uses of MIKE+. A PostGIS database may be located on a server for remote access and supports simultaneous access from multiple users
- Database setting and project setting: This is where you define the names and locations of the database (e.g. *.sqlite) and project (*.MUPP) files to be generated for the new MIKE+ project. Note: If you enter just the database file name, the *.MUPP file will be named and located similarly

#02 - Set the Coordinate System for the MIKE+ project
Next, click on the Coordinate System tab from the New Model Setup dialog to define the Coordinate System for the new MIKE+ project and database (Fig. 3). Please note that MIKE+ works with projected (and not geographic) coordinate system types.

We recommend you set the coordinate system for your MIKE+ project before importing full MIKE HYDRO River or MIKE 11 setups. To determine the appropriate Coordinate System:
- From MIKE HYDRO River: Set the MIKE+ coordinate system as you would in MIKE HYDRO River using the ‘Select file’ button on the Coordinate System tab of the New Model Setup dialog (Fig. 4)

- From MIKE 11: Check the Map Projection and Working Area dialog from the Network editor (Fig. 5)

If the setup of the river model you wish to migrate into MIKE+ is set to ‘Local Coordinates’ or ‘Unknown’, you may keep the ‘Local Coordinates’ setting in MIKE+. However, this may prevent the use of publicly available background map layers as overlay information for the model in MIKE+.
We recommend you instead view the migration process as a chance to properly define the coordinate system for your river model to be imported into MIKE+.
#03 - Finalize the creation of the new MIKE+ project
Click OK on the New Model Setup dialog to create the new MIKE+ project. Two files will then be created:
- Database file: Will be an SQLite (*.sqlite) or a Postgres database. This essential file stores actual model data. In MIKE+, any changes to model data are autosaved in real time – i.e., a change to a parameter is instantaneously reflected in the database
- Project file: The *.MUPP project file stores supplemental information such as GUI window layouts, map symbology, additional layers added to the map, etc.. To save changes related to this project information, use the ‘Save’ button in MIKE+

Prior to importing full MIKE HYDRO River or MIKE 11 setups, you may also modify the Coordinate System settings for the newly created project in MIKE+ via the Coordinate System editor (Fig. 7).

After configuring the new MIKE+ project, you are ready to import your full MIKE HYDRO River or MIKE 11 setups into MIKE+ using the tools provided.
It’s easy to create a new MIKE+ project in preparation for the migration of MIKE 11 or MIKE HYDRO River models. Just remember:
- A MIKE+ project includes a set of files (i.e., database and *.MUPP). Essential model data is stored in the database file. It’s important to set the appropriate Coordinate System for the MIKE+ project before importing a MIKE 11 or MIKE HYDRO River model setup. If the coordinate systems differ, the imported river network will be re-projected to the MIKE+ coordinate system
- Changes to MIKE+ model data are autosaved and will be instantaneously reflected in the database
