   * **Tru64 and Digital Unix** We can use both AdvFS and Logical Storage Manager to migrate you from your old to new SAN. Be aware that Alpha systems cannot use anything faster than a 2Gbit HBA. So, you'll need to keep a switch around capable of that lower speed. You may also need to adjust your buffer credits on the new switch to compensate for that old infrastructure. However, the upside is that with both AdvFS and LSM we can do the migration with no downtime.    * **Tru64 and Digital Unix** We can use both AdvFS and Logical Storage Manager to migrate you from your old to new SAN.

   * **IRIX** We can use either CXFS or the XLV volume manager to migrate your storage on IRIX with no downtime. If you are using XFS or EFS filesystems directly on disk slices, we can still perform your migration but you should expect some outages as the old storage is deprecated.    * **IRIX** We can use either CXFS or the XLV volume manager to migrate your storage on IRIX with no downtime.

 +==== What Have You Guys Migrated Before? ====
 +
 +We have done migrations between all major storage vendors equipment. On the old/legacy side we have seen a lot of EMC Symmetrix, NetApp 7-series, and Hitachi USP-V SANs. As far as newer gear we've landed on, it's typically been EMC VMax, Hitachi F-Series, Pure Storage, Dell Compellent, NetApp Cluster-Mode gear, or HP 3PAR. Not all newer SANs will support some of the special features required by OpenVMS. So, check with your vendor first before dropping any money on new storage.

 +On the switch side of things we are very familiar with Brocade switches which is mostly what we see in the wild. We also have had multiple experiences with Cisco MDS, Juniper, and Qlogic. Every now and then we'll see old McData switches and have had to deal with their quirky behaviors.
