Hi KOHA community,

We're reaching out for some guidance on migrating our data from a very old installation of KOHA (version 3.22) to a newer and updated version. We understand the significant leap this represents and would greatly appreciate any insights or recommendations you might have!

Specifically, we're hoping to learn about:

Recommended upgrade paths: Are there specific versions we should target along the way, or is a direct jump to the latest version feasible?
Data compatibility: Will our existing data structures and formats transfer smoothly to the newer version, or will significant adjustments be necessary?  
Available resources: Are there any official KOHA upgrade guides or community-developed tools that can assist with the process?
Professional migration services: If DIY migration seems daunting, could you recommend any reputable companies or consultants who specialize in KOHA upgrades?

We're committed to modernizing our system and enhancing our library's operations, and we believe a data migration to a newer KOHA version is the key. Any advice or expertise you can share would be invaluable!

Thank you in advance for your time and support.
