Citrix's AppDNA is application migration software, that has been discontinued.
I believe it would work well with continuous replication in a DR scenario with no time limits and having the ability to fail back is a bonus, but in a one off move the decision to restrict the time it can sync for has proven to be an issue for us.
Desktop Operating System upgrades and migrations to ensure installed applications are compatible with the new environment. If an environment does not have a lot of locally installed applications and heavily dependent on web applications, cloud applications, and Microsoft App-V, then AppDNA is not going to be beneficial in that organization.
Citrix AppDNA has a user friendly interface for admins to use and the product is updated well by Citrix Support.
It does not take a lot of resources to deploy AppDNA and can be done within a work week even for a large environment.
The reports not only show compatible and incompatible applications, but provide suggested solutions for incompatible applications to resolve and make them compatible with new Operating System.
If you have Citrix XenApp or XenDesktop Platinum, AppDNA is included and no additional cost.
License management is poor and the online system is very restrictive, We are using a one time "Move" product that has a fixed life ... but sometimes in a small team other high priority tasks come along.
We lost all access to all licenses in the portal and all support because we hadn't used them in ninety days. Very poor service. We did get access back eventually but it took a lot of "bargaining".
Failover isn't always as smooth as it could be. VMDKs don't release properly and the move fails and has to be done manually. Not hard just frustrating. VMWare to VMWare.
Citrix AppDNA should get more frequent updates on application compatibility list and provide even more detailed suggestions for fixes and perhaps auto-fix feature for some applications.
Compatiblity with legacy Operating Systems could be expanded to include more applications and OS to increase usability.
A good essential tool that should be marketed more by Citrix to organizations for usage beyond Citrix environment. Most non-Citrix IT personnel and management are unaware of the benefits of AppDNA and it's ability to help with desktop Operating System migrations.
Cabonite Availability is a very practical and useful tool that can help any business weather any type of IT disaster. The ease and quickness of restoring data helps us provide as seamless an experience as possible. Many times our customers will never know there was an outage. This brings confidence in our brand and improves our organization's standing and reputation.
Once through to support it is very good and they have assisted us through a number of issues. I don't always think that they provide a solution, more a workaround, but in a move situation where each copy is moving once, that isn't an issue. I'd be more concerned if we were using it to manage a DR scenario.
Zerto is a very nice tool when performing virtual to virtual replication. If you were to add a physical server in the mix, it would not be able to handle that server or the data on it. Veeam is a way is similar to Zerto where it only has the ability to handle virtual to virtual replication. The big difference is that it's not continuous replication. It uses a snapshot technology to grab the changes from the last snapshot and replicate that over.
AppDNA is more robust and provide a nice report of application compatibility list to review and segment verified applications from problematic applications. It takes one step further from the Microsoft Windows Migration Tool by providing solutions to fix the problematic applications.
AppDNA was relatively easy to deploy with a small team of 3-4 support IT personnel and took a week to deploy and another week for us to configure and use.
Great tool to cut down on manual process of testing initial application compatibility before system upgrade.
If you are a Citrix Platinum customer, there is no reason not to use this tool and a great way to consider upgrading to Platinum if you are an Advance or Enterprise customer.
For a single large organization (over 3000 desktops), if you are planning a desktop Operating System upgrade you need to take a look at AppDNA.
