Migrating data from older LTO (Linear Tape-Open) generations to newer ones is a process that helps to preserve and ensure data accessibility. Here are some things to consider when migrating LTO data

Compatibility
LTO tape drives are only backward read compatible with two generations and backward write compatible with one generation

Data integrity
Migrating to newer LTO generations, like LTO-9, requires careful planning to ensure data integrity. This is especially important because LTO-9 has increased capacity and speed

Migration strategy
A traditional migration strategy involves restoring data from older LTO tapes to a primary disk storage system, and then backing up the data to the latest LTO generation. This process should be performed over time in the background

Planning
When planning an LTO migration strategy, you should note the number of tape cartridges in each format, the names and versions of the backup applications, and the age of the oldest data sets.
