Hello Christoph, " I could do it with a copy-job but it would take months to complete because each job is first restored and then written to the new tape."
This is not accurate. The Bacula Copy job is able to read from one tape and write to another one, inline. LTO tape is relatively cheap and usually have a 30 year life expectancy. I would keep the LTO4 environment and media read-only, and start a new LTO8 backup life. But of course, there are always someone to create cumbersome business requirements or policies.
