You can do this programmatically. The table `tblContentSoftLink`contains information about what pages has a link to your external URL. From code, you probably want to look at the SoftLinkRepository.
Load each page, loop through all xhtmlproperties and update the link.
Thanks very much Tomas!
Is it possible to bulk update outgoing external links in Episerver content, including external links in the content of TinyMCE fields? We have some 1300 links going to an external service, of which the URL will change. These links are spread out over many Episerver pages.
Is there an existing tool for this, and if not, is it possible to do this programmatically?
