Changing a Column Type
If the column types have the same representation in Sync Rules, the type can be changed freely without issues (for example changing between VARCHAR and TEXT).
Other type changes, for example changing between INT and TEXT, require more care.
To change the type, it is usually best to create a new column with the new type, then remove the old column once nothing uses it anymore.
When changing the type of a column without renaming, use a column type mapping to still use the old type for existing client applications.
