The old card has not changed standards
A familiar card can look like the obvious item to reuse when moving from Switch to Switch 2. Nintendo’s compatibility table draws a firm distinction: ordinary microSD is not the new console’s digital-game storage. Its limited ability to load screenshots and videos captured on the earlier system does not give it that game role.
Choose the named card for install space
SanDisk’s Nintendo Switch 2 512GB card is identified in its official datasheet as microSD Express. Express is the important qualification before comparing capacity. The console’s support for cards up to 2 TB does not turn this particular product into a 2 TB card, and a large capacity printed on an older ordinary microSD does not make it Express.
Nintendo also requires an internet system update the first time an Express card is used. Include that setup condition in the plan if the new console is being prepared somewhere without a connection. It is not a reason to assume an existing ordinary card will work instead.
Install space is not progress backup
Nintendo keeps game save data in system memory. An Express card can hold downloaded software and content, but buying more card capacity is not a way to move that progress onto removable storage. That matters when someone says they want a card “for their saves”: ask whether the shortage is game-install space or whether they actually need a supported save-data arrangement. The SanDisk product is a concrete candidate for the former; it does not turn those two needs into one.
