text: **12.6 Migrating between providers**
  
  IBM Spectrum Virtualize V8.1 introduced support for simultaneous use of both USB flash 
  drives and a key server as encryption key providers. The system also allows migration from 
  configuration using only USB flash drive provider to key servers provider, and vice versa. 
  
  If you want to migrate from one key server type to another (for example, migrating from SKLM 
  to SafeNet KeySecure or vice-versa), direct migration is not possible. In this case, it is 
  required first to migrate from the current key server type to a USB flash drive, and then 
  migrate to the other type of key server. 
  
  **12.6.1 Changing from USB flash drive provider to encryption key server**
  
  The system is designed to facilitate changing from USB flash drives encryption key provider 
  to encryption key server provider. If you follow the steps that are described in 12.5.1, “Adding 
  key servers as a second provider” on page 648, but when completing step 2 on page 648, 
  select**Yes**instead of**No**(see Figure 12-65). This action causes de-activation of the USB 
  flash drives provider, and the procedure completes with only key servers configured as key 
  provider.
