Nava Certus 1.3: Migration deltas, Synchronization

Customers using Nava Certus, may have noticed a few logistical complications with extremely large migrations. If a migration was large and the source files were still in used by users, then by the time you migrate the data there will be new versions of some files at the source.
In the past, we recommended to split up migrations into manageable chunks and to enforce a ‘freeze’ on the source during the migration.
Today we have a more ideal solution. We’re happy to release Nava Certus 1.3 featuring a new “Continuous Mode” option that enables two use cases: Delta migrations & One-way Synchronization.

Delta Migration
One the main stage of the migration has finished, a delta migration allows for the migration of only the changed files. With this functionality, each migration can now have a last “delta migration” phase shortly before the go-live.
One-Way Synchronization
With the one-way synchronization use case, the customer would like to continuously update the destination as files at the source are updated. When the destination is set to Google Drive,
More Details
As you can see on the left, there are three configuration options we’ve added:

Enable Continuous Mode: With this option enabled, after migrating the initial set of data, NC will go into “Watching” state and monitor the source for changed files and periodically begin to migrate the changed data. For the Google Drive destination, modified files are appended as new “Revisions” to the existing file in Google Drive, preserving the previous version of the file.

Detection Method: We support 2 modes of detecting changes: Datetime and Checksum. With Datetime, […]

Dropbox migration; Cloud migration to premise

Nava Certus 1.2
Today, we’re announcing the latest version of Nava Certus. With this release, we bring support for migration to and from Dropbox as well as migration from cloud storage to local premise servers.

We’ve been hard at work trying to realize our goal of making Nava Certus synonymous with cloud storage migration. If you have a request for a particular source or destination, please don’t hesitate to respond in the comments.

Full release notes available here.
Dropbox Migration
Dropbox is now available both as a migration source and destination. Some of the use cases for this are:

Do you have a different Dropbox migration use case? Let us know in the comments.
Cloud migration to premise
We realize that organizational cloud computing strategies can change over time. What made sense a few years ago may not anymore.  For this reason, we’d like to ensure that you’re not locked in and married to your cloud provider. Combined with the document conversion feature introduced in NC 1.1, we can now support a full migration and back-up of Google Apps data in an independent format.

Use cases to consider:

Change in Cloud Strategy

You have a new IT executive and he/she wants nothing to do with the cloud. Or perhaps you’ve merged (or been acquired) by a company that doesn’t subscribe to the cloud mentality. Far too common from our experience. Problem? No problem!

Disaster Recovery

You like your cloud storage, but want to ensure that you still retain your data in a disaster that may affect the cloud provider. Consider the case of Nirvanix, a cloud storage company that […]

Nava Certus 1.1 – Migrate from Google, File Conversion

Over the past month, we’ve been working on a few new features for Nava Certus. After a lengthy period of testing, we’re happy to finally announce Nava Certus 1.1

The main features in this release include:

Google Drive Source

Many new use cases are enabled with the addition of the Google Drive Source feature, such as:

File Conversion

When migrating to Google Drive, some customers would like to have the ability to convert documents, such as MS Word, Excel, and so forth to Google Docs format. We’re enabling this feature in 1.1 and allow you granular file conversion settings.

In addition to the new features, we also fixed a number of bugs. Visit our support forum for a full version of the release notes.

As before, Nava Certus is available for free for evaluation purposes.

Nava Certus Migration to Amazon S3, Permission Analyzer

Hooray! Today we’re releasing the latest version of Nava Certus, our cloud storage migration software. Have you tried it yet? If not, then why not go for the trial and you can migrate up to 1GB for free. Today’s release contains the following new features:

Support for Amazon S3 storage: Due to popular demand, we’re now supporting migration from Windows file system to Amazon S3. Simply configure the migration job for S3 and within minutes you can be uploading your files to Amazon S3. Don’t worry about lost files, with our Migration Integrity report you can provide your boss/customer with a full accounting of what exactly was migrated (and what was not, including the reason). Amazon S3 migration also supports preservation of permissions.
Permission Analyzer Tool: Complicated migrations, where many users are involved, require a little bit of planning. Now, a built-in Permission Analyzer Tool can list all of the users and permissions present at the source. This will aid you greatly in creating the user mapping file and thus speed up the migration preparation time.

Migration Integrity – Ensuring Chain of Custody with Nava Certus

If you are planning a Google Drive migration and require assurance that the files at the source are exactly the same as the files at the destination, then you may be interested in our “Migration Integrity” feature.

One of the features that we designed into Nava Certus from the very beginning is called Migration Integrity. While this feature is not the most visible to the user, it is perhaps one of the most important for our enterprise customers that may want to ensure a certain chain-of-custody within the migration process. The “chain of custody” may be something that is required by your company’s internal policies or by regulation.

Specifically, the integrity feature provides assurance that every single file that has been migrated has not been altered in any way. For every single file that we migrate, we calculate a cryptographic hash which we later correlate with Google’s own hash (which automatically gets generated for any uploaded file). If the hashes match, we consider the migration to have been a success. If the hashes don’t match for any reason, the particular item will be marked as failed.

Be on the lookout for the next release of Nava Certus, which will feature a “Migration Integrity” report. This report will list every single file migrated, the hash at the source, the hash at the destination, and any errors. You can provide this report to your auditors as proof of the integrity of the migration.

HOWTO: Migrate File Server to Google Drive with Nava Certus (Centralized)

Do you need to migrate a large quantity of files to Google Drive? Have you tasted the frustration of the “manual” approach? Well, why don’t you try Nava Certus? It is the ultimate Google Drive migration tool. It moves files, copies permissions, recreates the directory hierarchy, and lets you print pretty reports for your boss. And you can take all the credit.

Here we show the “Centralized” configuration, where all files go to a single destination Google Drive. NC will migrate the specified file(s) only to Google drive of those domain users who are granted at least one type of permission on that file. Using a preconfigured mapping file, NC will map the file permissions along with migrating the file to respective Google drives.

To create and configure a Centralized migration:
General tab
In the General tab, configure the general settings of the migration.

Mandatory settings:

The Email Configuration section is optional and is used if you only want to receive email notifications on errors or slow performance.

Source tab

There are few settings here:


The “Source Root Folder” in reality can be any folder mounted in Windows. As such, you may also consider Dropbox, Amazon S3,, and any other cloud storage which appears as a mount point in Windows. There is a small caveat about permissions in these cases, but if you don’t need to preserve permissions for Dropbox and such, then NC is a great tool for such migrations. (Note: We’re always developing new “native” source types, so check back often.)

Destination tab
For destination type, please select “Google Drive” (This is the […]
