Moving Non-rollover Volume to Rollover

asked on December 4, 2019

I have a client who, due to space issues, needs to move an existing non-rollover volume to one that is rollover in order to better parse out space for the future.

 

I am hoping to gather some feedback in regards to best practice of migrating.  We are working with one 800gb non-rollver volume.

 

1. In order to keep production moving during the day, would it make sense to create the new rollover volume, point any new documents/etc to go to that new volume.  While keeping the old volume as read-only and migrating portions over during off work hours.

2. Is there a recommended size of data to migrate at one time?  For example, moving 20gb of data at a time to reduce room for error.

3. Is there any other method that would make more sense that I am missing?

 

Thank you for any advice/feedback anyone may have!

I think you're first step is definitely going to be setting up a new volume and making it the default to address anything new moving forward.

As far as your existing documents, one possibility would be a nightly workflow that searches for a limited number of documents and migrates them to the new volume in batches.

Whether or not you make the old volume read-only is up to you. If you do that, I believe it makes all of the documents read-only so you wouldn't be able to make any changes until they were migrated. Unless your users are choosing a volume, it would use the new default so you don't necessarily have to worry about a lot of new files being added.

In my opinion the file counts are an equally important factor for migration. The number of page images, electronic files, text files, etc., for those documents will affect how much content needs to be migrated.

You might want to start with a small batch to get an idea of how fast it runs because there are a lot of factors that could impact speed (disk IOPS, if the drives are on on the same server or not, etc.)
