I have two site collections, with a bunch of sites under them. Now I have been asked to change the language of the site.

I have successfully installed the language pack, and completed all the tasks related to it.

Now I want to change the language on the existing site. I have found infomation saying that I cant do this on already installed sites and site collections, since their template is set to the original language.

I wonder, is it any possibility to keep the content of the existing sites, and only install the templates again?

No, there is no supported way to change the Site Collection Default Language once it is created.

  • So you can delete the exisiting site collection and recreate the site collection with correct language, but this way you will lose all content.
  • other way, you can create another Site collection with new language and then manually copy the data from old site to new.
  • Another way, just change the User language settings, see if that solves the problem.

Note: Use on your own risk.

  • Another method is to directly update the template languge in SQL server. this is totally unsupported by MSFT. But what I am thinking, Copy the Site collection and restore in the test farm and change the language using SQL query. To test it.
