Remove the 260 character limit for NTSF Paths in Windows Server 2016 and Windows 10

With the Anniversary-Update on Windows 10 (Version 1607) you have the option to remove the limit for the 260 character standard.

Within the registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem you will find a D-WORD (32-bit) named LongPathsEnabled.

It is deposited with the value 0. Change it to 1 to activate the option.

The same change can be implemented with a GPO.


The practival utility

Disadvantageously, this doesnt effect the system the way it is intended.

Some applications can gain profit from this setting (PowerShell). For other Windows-Standardapplications, like the “explorer.exe” or “cmd.exe”, this setting does not work. Under this terms, there is no real way to disable this limitation for the use within migRaven.



The use of this settings is always at your own risk.
Windows used a #define-constant labelled as MAX_PATH to save path-names, while changing the size of Character-Arrays (Strings).

The remove of this limit can lead to Buffer-Overflow,
generally leading the application to crash.

Account-Report / E-Mail Configuration

1. Account Report

The migRaven WebClient can show and export specific User-Information.

In the search box Selevt an account you can search the database for single user.

You can chose to view the evaluation in a list or to export it within a .xlsx file.
If you chose to export it, you will receive a mail with the download-link for your .xlsx file.

Instructions: migrating from Novell to Microsoft

1. Read trustee information from the Novell server 

1.1. Source: Novell Netware

1.1.1. Output Permissions with the Trustee.nlm command

Novell Netware does not have any trustee-database.xml. The trustees however can be read with the console command trustee.nlm.
An example for the syntax is:

TRUSTEE /ET /D SAVE VOL1: sys:\trustee-vol1.csv

/ET for permissions, without ownership
/D for directories, without files
VOL1: permissions and directories from this volume
sys:\trustee-vol1.csv is the output file

If the output file contains unwanted information other than the trustees, you can generate a file reduced to TRUSTEEs with:
FIND “TRUSTEE” trustee.csv > only_trustee.csv

migRaven Release Notes

migRaven Version 5.0.1003, Database-Version, Release Date 05/17/2016


Prior to installing this new version of migRaven, any previous versions, currently installed, will need to be completely removed. To begin with, stop the “migRaven Database” service.
Then “migRaven” and “migRavenDB” can be uninstalled using ‘Programs and Features’ from the Control Panel in Windows. Finally, the contents of the following directory need to be deleted: “c:\Program Files\migRavenDB\DB\data”. It contains data from the old version of migRaven, which is no longer compatable with this release.

After these steps have been completed, the new version and database can be installed (in any order).






The biggest change in this release of migRaven is the “GPO” project (Group Policy Object), which migrates Share permissions assisted by Group Policies. This makes it possible to process enormous amounts of data in under an hour. The new permissions are saved to the original Share and the old permissions are deleted. This is in contrast to the “Redesign-Project”, which requires the creation of a new, empty Share. Therefore, the need to copy data is eliminated.

Go to “Group Policy Project

View – visual interface

The view is the visual representation of the authorization structure, once the read (initial state) and after the “Design & Work” the planned authorization structure (new state).

1. Initial state – the read authorization structure

The “View initial state” is the only component of the project type “Migration per Scan”. It shows the authorization structure of a read Windows-Share.

After reading the output directory, migRaven lands in the View – initial state.
You can move on the left side by the directory structure. On the right hand side you see the authorized groups and accounts and their rights for a directory selected on the left hand side. Below that you can display the members of the groups, the accounts, you may change or all members entitled to this directory.

Table mode

1. Mapping Permissions

The first step in the table mode is the mapping of permissions.

Only then can you fill your table to set permissions.

2. Filling Table

The data is inserted here depending on the type of project. In case of “Scan Your resources“, the data is taken over from the initial state with the help of the button “Start filling”. The excel tables can be read in the “Import or create a table” and “Novell-migration“.

Further in all the types of projects it is possible to manually insert rows and change values. Here you must pay attention to the syntax of the field content and the column headers.
