i want to change a custom Field

test= fields.Integer(string="Test")
to
test = fields.Char(string="TEst")

if i do this it works but all existing Values will be lost in DB. Is it possible to make this without loosing the existing values? (castet to Strings in DB)

You can change fields from integer to char. Then all values store in test_moved0(created new column). You can run below update query to fill values in new column.

update table_name set test = test_moved0;
