DATA & APPLICATION MIGRATION
There are four main types of data migration: Storage migration, Database migration, Application migration, and Business Process Migration. Business Process Migration and the journey of IT transformation are vital to every business and should include IT security.
How it Works
The most common type of data migration Nth Generation customers request is Storage migration. Block (FC SAN) and File (Ethernet SMB/NFS) migration are common, with Object/metadata important for Cloud migration. In the modern era, database and applications are typically virtualized VMs, and the hypervisor will have V2V and P2V from physical. For this reason, virtualized database and application migration dovetail with Storage migration which is the primary focus for Nth Generation.
Block data is tuned for virtualization performance, and if same hypervisor simple best practice or replication, or ensuring backward compatibility for generations of processors. Migration between hypervisors is typically supported by the target hypervisor providing tools to migrate to their environment. Migrating to cloud can mean migrating some data, but also fresh build of the VM optimally for its destination.
With advances in Dev/Ops and effort to publish standard APIs, open source and migration tools, there is often more than one way to migrate, yet for some cost a faster, more efficient method, scripting technique or proprietary tool that results in overall cost savings.
FC SAN or iSCSI “block” datastore migration and File migration from retiring source to newly purchased target are common requests of Nth Professional Services. In other cases, when the customer has interest in full-featured data analysis and owing the migration we may recommend partner software tools. Larger multi-terabyte NAS file migration from one vendor to another is commonly requested.
S3 does not belong to Amazon. There are many S3 Compatible storage vendors and it is commonly expected that backup and recovery will archive or migrate to S3. Tape is being further replaced by multiple offsite and more recently immutable read-only archive, which are required for a business to recover from ransomware. Investigate methods of migration that dovetail with managed data archive.
Vendors have proprietary file systems. For file data migration it is very important to properly migrate the access control lists (ACLs); lists of access control entries (ACE). Each ACE in an ACL identifies a user and specifies the access rights allowed, denied, or audited for that user. They can look slightly different from source to target, so it is important to maintain the same effective permissions, since most NAS file vendors store and present information differently. Some customers required complete audit reports to ensure the migration was successful.
WHY YOU NEED DATA CENTERS
Migration to newer architectures should mean innovation. Improved features and performance of a new storage architecture. Moving to scale out performance and pay as you grow consumption models typically involve adding a node for more capacity and performance.
Migration between block, file and object is the more specialized relating closely to what customers use for their archival backup solutions. The most popular backup and recovery vendors may methods of archive and manage metadata for retrieval. Data analytics vendors may offer management across disparate filesystem, file types and extend to object or cloud archive. A company’s data is one of its most valued assets and as data grows exponentially, migration blends with archive, backup and recovery. Products and Services which help a business understand where to save across multiple on-premise and public cloud, across multi-cloud, are becoming increasingly valued.
Business process migration is generally for improvement. Upgrading, replacing or migration from legacy systems drives digital transformation and better business outcomes.
BENEFITS OF SD-WAN
Improved data and file retention and analysis with potential data management strategy
Workload migration to newer platforms for improved performance, capacity and features
Platform innovation often improves IT responsiveness for more business agility
Migration services and tools may ease, speed and bringing cost savings in the process
Higher reliability, availability, and scalability (RAS) of solution (migration target)
