Manually updating theme but can't find translations

I currently am migrating from Stiletto theme (1.4 to 1.7) and due to some custom code I had done to improve the SEO speed, I am not able to automatically update the theme (very annoying btw).

So I downloaded the new theme and am manually copying some of the json/liquid from my current theme (1.4) and adding it to the new theme (1.7). All the updates seem to be fine and the sites look the same but I cannot find any of my translations. My whole current theme has a full Spanish translation of everything, manually done by me but the new theme doesn’t translate and I don’t know how to fix that.

Hey @cspineda , as themes all differ there is not currently a way to automatically match translations from one theme to another, so they need to be manually transferred. To do this, make sure the ‘old’ theme (with translations) is published, then export your CSV - Settings > Languages > Export. This will give you your manually entered translations - which you could then copy across. An alternative is to use auto-translate in the Translate & Adapt app (which you can do just for the theme by clicking ‘auto-translate’ in the app on a Theme Assets or Theme Sections page) and then correct the auto-translations - might save some time.

Theme updates - yes that’s definitely an understandable painpoint. This is part of the reason theme app extensions were introduced, as they enable app capabilities without directly editing theme code (which is what takes themes off the upgrade path). They are not universal yet, though, unfortunately.
