Upgrading from classic to S - Keeping permalinks alive?


I am currently working on moving our omeka classic to omeka-S and I was wondering what was the best solution to keep our current links alive.
I have upgraded omeka classic to omeka-s and kept a property holding the id from omeka classic and was wondering what was the best way to use them (having http://1886.u-bordeaux-montaigne.fr/items/show/76462 to still work when omeka-S will replace omeka classic on this server).

Using a .htaccess RewriteRule that will use the old id to build and advanced search Url querying the omeka_classic_id property that I have transferred to omeka-s ?

Have you got any other idea?

Best regards,
