Hi,

How to work with migration module 

<moduledir>

`-- migrations

|-- 1.0

| |-- pre-update_table_x.py

| |-- pre-update_table_y.py

| |-- post-clean-data.py

| `-- README.txt # not processed

|-- 5.0.1.1 # files in this folder will be executed only on a 5.0 server

| |-- pre-delete_table_z.py

| `-- post-clean-data.py

`-- foo.py # not processed

This similar structure is generated by the maintenance module with the migrations files get by

the maintenance contract

Help me out
