Migrating away from EAS?

[r0bsk1]

I have code in development that is very close to completion to migrate all email in the EAS doc stores in to PST for importing in to your new archiving environment.

Deleted stubs, duplicates stubs and stubs that don't belong to the mailbox are all dealt with.

Please contact me for more details.

Hello r0bsk, sounds interesting. There are only a small ammount of Tools aviable for EAS like Transvault or our ArchiveObjectRestore. There are many pitfalls - are you supporting multithreading? Are you also able to Support all Document Store types and Databases?

[r0bsk1]

Hi Martin, multi-threading is supported by simply running multiple sessions of the code. Might seem like cheating but it's far simpler to manage.
For the time being this is only for SQL databases as that's what i have in my environment.
For a successful migration to PST we have found that the docstore of choice is single file archive (HSM). Any other type will need converting to HSM which usually requires a storm task to move the data from one store to the other. Again, it might seem like cheating but it's far simpler to manage and control.

[r0bsk1]

We looked at transvault to move our data but they appear to have a low throughput of data and estimated it will take 3-4 years to migrate the data. We need to migrate away from EAS before 2015. My method will extract all data in approx 12-18 months.

[Bagot, Janet]

I find it hard to believe that you can do any better than TransVault – We have worked with it on numerous EAS migrations and not had any issues with performance.

 

Also they now have a direct extract method for situations where EASIIS is not working – plus they can work with Day Container files – extracting to HSM using Storage Manager is not quick!

Janet, having not used transvault i'm only refering to performance stats they have quoted. They also quoted near £500,000 for the software.

My method does not require IIS and pulls the emails directly from the docstore. It simply needs SQL and the store online. Extracting a day archive doc store for 1TB of data is a task that can be completed overnight so there's no waiting around. It doesn't need to be quick.

I would be interested to know how many TB’s you have to migrate.

I agree with Janet,

 

it is not as simple as it Looks and Transvault and we self develope our Solutions for many years. We also restore directly from the document stores and there are as many pitfalls as customers... For Example, you Need to take care for the Folderstructure, for already deletet Stubs, for changed read/unread Status or other attributes that changed after the original was archived.

 

For a large restore it is also very important to take care for a good reporting and errorhandling. It takes us years to get this all sortet...

 

Martin

 

 

[r0bsk1]

I'm well aware of the complexities. I have supported EAS for many years and solved many issues that autonomy gave up on.
The folder structure is maintained in the PST.
Deleted stubs are accounted for.
Read status accounted for.

So basically what you are saying without even seeing what i have developed or knowing how long it's been in development for is there is no way I could have made migration code because it's taken you and/or someone else years to develop something similar?

 

 

[r0bsk1]

Currently we have 85 docstores with an average size of 500Gb. Approx 200 million individual items.

Thruly not - I really believe that it will be possible ;-) it is an similar way as we start develope our Tool and as far as i know, Transvault also...

 

 

 

 

[Bagot, Janet]

The TransVault pricing for software for 40TB of compressed data in EAS should not come anywhere near £500,000

 

For 200 million messages to PST I would have estimated about 20-30 weeks of processing for 1 TV server

 

However you have obviously put time and effort into finding another way forward so I hope your migration goes smoothly

Apologies it was £400,000 for a managed migration. £250,000 was for the software.

[r0bsk1]

Apologies if i misunderstood you but i can assure you it does work. There's alot riding on my method and it cannot fail.

 

 

[r0bsk1]

The latest code developed today takes care of any EAS subs that are store within the Exchange archive mailbox.

[Jo Woodley]

I may of missed it in the conversation thread but have to ask how much data you have archived to say it would take 3-4 years. With most established sites even using native restore then re archive I've not seen it take that long and having worked with Transvault for a number of migrations now it takes far less than native export to PST or restore to mailbox and re archive with our product
