You can migrate to a target volume that is larger. The source can be a non-EMC array, but target must be EMC. It has been out for quite some time, meaning it is a proven tool with much good documentation, but is also a little outdated. This is a free program that works with variety of operating systems. Let’s look at them in more detail: Host Based Open Migrator Obviously, the tools discussed here are not the only ones, but these are the most commonly used. What methods can we use to migrate? Host based? Array based? Combination of both? We have quite a few proven and solid tools to choose from. If it weren’t for tech refreshes and the need for better performance, it’s doubtful they’d even consider doing a data migration, let alone pursue virtualization. And even if they can be, they are critical enough that the whole “if it ain’t broke, don’t fix it” thing comes into play. Many of our clients have legacy systems and applications that cannot be virtualized. It’s definitely not as crazy as it used to be, but plenty of migration work is still done regularly. At any given time I’m involved with a couple of migration projects. Many of these clients are implementing Unified VNX models and we also need to have a data migration strategy for NAS (moving from another NAS platform or a physical file server to a VNX/Isilon). However, there are still plenty of clients with physical hosts, and they need to figure out how to get the data from an older array to the new one (VNX/VMAX).
What used to require a lot of planning and create a lot of anxiety has been reduced to a few clicks and no downtime! Data migration projects I’ve been involved in have declined significantly over the years, and I’m not complaining-because doing data migrations is not how I like to spend my nights and weekends. We simply stand up the new array and present the LUNs to the ESX cluster and the VMware dudes take over from there. It is true that VMware Storage vMotion has greatly changed the data migration landscape.
By Prashant Shah Data, Migration, Storage, ToolsĪ blog post about data migration in 2014?!? Isn’t everything virtualized and Storage vMotion the way to go? And these days, if the topic doesn’t have the word “cloud” in it, is it even worth talking about?
