1. Create project and read in directories
In migRaven, one always works with projects. A project is a logical unit, which is to be processed, for example a share or a directory below a share. Best is the point which is mounted in case of users or integrated into the DFS. Thus one ensures that all Authorizations - including the list of authorizations - are correctly created by migRaven, Via the title "Administer projects", you arrive at the point, where new projects can be created, processed or deleted.
The prerequisite for creating new projects is at least the domain was scanned once.
If you define the individual shares as independent projects, then you have time to process it in peace and copy the data into new directories "Step by Step" and then assign to the users.
For example Project1: "\\ server \ data \ management \ accounting"
Project2: "\\ server \ data \ management \ purchase" etc.
Then enter the UNC path till the directory (project) to be scanned. Please check once again if this path is attainable, above all with your login data.
Please consider: According to your Windows login, MigRaven can only scan the directories, which you may access, therefore you must execute the program always as administrator.
1.3. Scan depth and threads for scan
These settings have significant effects on the size of the database and the speed of the scan.
1.4. Scan depth
The scan depth should be as low as you can to select and set the authorizations in the folders. (The more deep a scan is, the longer it takes to scan and the larger becomes the database.)
1.5. Threads for scanning
The more threads you select, the higher the process load is. Recommendation: max. 2 threads / core. You immediately experience while scanning there are too many threads. This makes the java process noticeable.
3. Prepare new groups in migRaven
3.1. In this step the groups are formed and nested by migRaven within the database.
In addition to this, the following must be determined in the group configuration:
- The type of group
- The naming of the groups
- How far should the list be right
- The storage location of the (OU) groups
The last step does not take place in the AD and / or on the file system, whichever
- The groups of migRaven are automatically created and nested in AD and
- The actual implementation takes place in the file system.
Hereby one complies with the group configuration (domain local or universal groups, list authorizations or not, etc.)
4. Create and nest new groups
In this step, the groups are finally created and nested in the AD.
4.1. migRaven carries out the following steps:
- The groups are created LIVE in the AD,
- The authorization groups with the list groups are nested and
- The users / groups are included in the authorization groups.
- The authorization / list groups are automatically stored in OU, which must be defined in the group configuration.
If these steps are completed, it has been completed in the next step through migRaven, Please be cautious of the fact that only the number of group memberships of the users increase. Please focus on the size of the Kerberos token.
5. Create Green Meadow
In order to design the complete process as easy as possible, the authorizations are not written on the original path, but migRaven creates a blank copy of the directory tree with the new authorizations.
Via the point "Deploy ACL", a new and fully authorized, but blank duplicate of the directory tree is created. This is the new final storage location for your data.
In case of this step, only the directories, which have received explicit authorizations via migRaven, are re-created and authorized with the appropriate already available groups.
A path must be prepared, which is the new data storage location after the replication of the data. This can be a complete new share or directory in an available share. When you set DFS, it recommends creating a new share, which must be linked to the DFS.
Only the directories are generated in the new path, which were processed before.
If source is \\ server \ share \ and is then below directories, then these are written under the new path: \\ server_new \ share \
For the new storage location, please fill in the predefined mandatory field.
5.3. There are two possible approaches for using the "Green Meadow":
- The "Green Meadow" includes the old data and functions as new storage location.
- The "Green Meadow" serves as a buffer and control storage location. After everything is controlled and found "OK, then the new ACLs are transferred to the old location.
In this step, the new directories are created and the rights are given.
6.1. Following steps are processed:
- The directories are created, for which authorizations are provided.
- Directories are provided for which list rights are only available for this folder.
- Underlying directories are created according to our configuration with authorization groups. The groups have been created for the authorization end point, but only here.
- In case of authorized directories, several authorization groups can be entered, one with read-execute-rights, one with read-write-rights and one with modify-rights. Authorization groups with full control rights should have exceptions.
- These rights are transmitted to the secondary directories.
- Secondary directories can get further authorization groups.
