I have a task to recreate a SP2019 on-prem farm. Originally it was installed with Polish language, so both Central Adm and the site are in Polish. Now the idea is to have the English version installed, but separately install Polish language pack, so Central Adm will stay English but the main Site collection will be in Polish.
The question is about data migration: can I simply backup & restore this SPSite on this new farm installation, or will there be a version mismatch?
If this is off the table, what other possibility remains? Manual recreation? Is there some PS script which could help me with migrating data?
