Option 1 (Transfer UVs)

Use the Data Transfer modifier, and select "UVs" under "Face Corner Data". Make sure you click "Generate Data Layers" so it has somewhere to put the transferred coordinates, and play around with the mapping type to find the best result.

Pro:

  • Allows re-using the same texture map(s).

Con:

  • Cannot automatically handle seams.

Option 2 (New UVs, Transfer Texture)

Unwrap the re-meshed model separately, and use Render Baking in Cycles, for "Diffuse" colour and with "Selected to Active", to transfer your original model's textures to the remeshed geometry's new UVs.

Pro:

  • Allows precision down to pixel scale.

Con:

  • Requires texture duplication, inefficient and lossy.
