VirtaMove (formerly AppZero), offers the eponymous VirtaMove Migration Intelligence Suite allowing the user to move legacy apps to modern, secure servers.
I think it's a great product. We apply Oracle GoldenGate to several use cases in our organization. 1. Business Continuity Planning, 2. Query Offloading through data replication to a reporting instance of our data, 3. looking into data transformations to help support various queries for different teams within the business.
Best suited for applications where installing from scratch is not an option or a very difficult one. Migrating applications that you are familiar with, you have support for or have done in the past, via AppZero, in my experience, may become more time/resource consuming. In my environment it makes little sense for example to migrate an Office Suite via AppZero. Good at collapsing tiers (e.g. old application whose demand has waned and it no longer needs to serve large number of users). The score is awarded is a bit misleading, AppZero is invaluable when you have no other choice but for mainstream applications its value drops.
When documentation regarding the implementation of an application is missing (e.g. old versions and support is prohibitive to obtain, or in case of homegrown applications) it becomes the tool available to perform the migration.
There is always a back-out option, and different approaches/attempts can be made.
Will provide you insight on what otherwise would be a "blackbox" application.
Allows you to consolidated multi-tiered applications into fewer/single tiers.
Once set up, it's very easy to use and keep running, it's getting to that point that can make it cumbersome to some. Also, depending on the data that you want to replicate, the configuration files can become quite cumbersome to maintain. Learning curve can be high for some who are not as experienced with databases and transactions.
Oracle Support for Oracle GoldenGate has been quite responsive and quite helpful in the few situations where we've needed it. Furthermore, the documentation on Oracle GoldenGate is so good that we often do not need to contact support with issues as the fix is already documented and able to be run by us without needing to open a ticket.
We've had Oracle consultants come as well for training days to talk about new features, parts of Oracle GoldenGate we may not be using and things of that nature. The consultants they send are great as they're very knowledgeable about all things Oracle GoldenGate and great resources for any questions or concerns you may have with the product.
We used Oracle University for our Oracle Golden Gate Training and it was top notch. We were able to turn our whole DBA team to Oracle GoldenGate newbies to Oracle GoldenGate troubleshooting experts in a matter of a few days, while this obviously did not come cheap, the company felt that it was worth the investment.
If Oracle GoldenGate is new to your organization, expose as many DBAs as possible to it. Having your whole team fluent in it will overcome early operational hurdles and allow it to more quickly become an accepted and supported part of your supported platform for your team that will enable the business to use it to its fullest.
We use Oracle Data Guard as a backup tool, but not for data replication. Data Guard is not suited for real-time data replication in our non-normalized reporting database nor for the database we are using for our upgrade project, as Data Guard is not able to transform data and is not able to synchronize data into different schemas, which is necessary for our project. Additionally, our project database is on Oracle 12g not 11i: I am not 100% sure Data Guard is able to replicate from 11i to 12g
I have not use any other application for this purpose. I've selected AppZero based on peer recommendation and found it to fulfill the functionality I was looking for.
Have never had any issues with scaling Oracle GoldenGate itself, however Oracle GoldenGate Monitor does have scaling issues, but with Oracle GoldenGate now able to be monitored by Oracle Enterprise Manager, this is no longer an issue, in my opinion.
In earlier versions, DDL support was limited as well as the need of primary key constraints in the source tables. This made me create partitions, sub-partitions, truncatations and perform other operations upon they are performed in source systems and I need to discuss with source system administrators and need to convince them to let them create primary keys for replicated tables.
But both issues are solved now.
Installation is straightforward, easy.
Deployed everything within Oracle Data Integrator.
Developing 1000 of ODI interfaces for loading into Operational Data Store took not more than 100 man/days. But, adding them to Golden Gate is taking not more than 5 man/days.
Management Pack and VeriData are additional packs for your management and data verification needs.
It has certainly proved to be a worthwhile investment. There were cases where to migrate an application several versions behind with lapsed support would've been a many zeroes expense. Done via AppZero, it was a LOT cheaper.
