netOffice Dwins 1.5 alpha is unstable and only for testing.
We do not provide an upgrade procedure for this version to webTareas 1.5 final version.
We suggest you make a brand new installation of webTareas 1.5p4.
Sorry for the inconvenience.

Is there any alternative to use the existing database with the Latest version. So that My data will be up to date.

Thanks

I have installed latest 1.5P4 version and by copying the each individual tables from the old database i was able to see my old data in newer version installed

Many thanks!!!!!!!!!!!!!11
