SAP xMII migration from 11.5 to 14.0

Hi Experts,

We are migrating from xMII 11.5 to 14.0. I have gone through the below links, latest CUG and got some idea about migration procedure and got few queries before I run the migration tool.

MII 11.5 migration to 14.0

xMII 11.5 Backup for Migration

1. What is migration tool version that we have to download for MII 14.0 SP04? Is the latest version is enough for MII 14.0 SP04?

2. Does the tool migrates only the project code files or migrate configation,security files as well?

3. I mean I want to know which files the tool would migrate and which files we have to manually migrate?

4. Can somebody provide any documents for migration procedure other than CUG?

Thanks in advance,

Eshwar.
