from the web2py command line to convert between data types shouldn't
be that hard.
of course, you "should" have your data types set out before the app
ever hits production so migrations like this usually mean deleting the

When you change a field type web2py automatically creates tmp column
of the new type, copies data, delete the old column and renames the
tmp column. This works great if you convert, for example an int to
string. How well it works depends on the database and the type of
conversion.

What about data type conversion though.
In rails this is why you have to define migrations in rake script.
Would it even be worth it for web2py ?
Could we load the database column to a csv file, have web2py automate

If you need to change a type the safe way if by deleting the column,
run admin, add the column again of a
