Beginners • Re: Can I just pop the old card into a new Pi?

If you replace like for like (not just with a 3B+ but one with the same board revision) it should just work.

If you have a 3B+ of a later revision you may need to update the bootloader related files on your SD card:

• Flash the latest RPiOS onto a spare SD card. Lite or full doesn't matter, neither does 64 or 32 bit.
• Grab a couple of USB card readers and a PC.
• WIth one card in each reader open both boot partitions.
• If using Windows and are prompted to format a partition do not do so as it will erase all data in the root (Linux) partition.
• Backup the boot partition of the old SD card.
• Copy the following files from the new card to the old one:
  fixup4cd.dat
  fixup4.dat
  fixup4db.dat
  fixup4x.dat
  fixup_cd.dat
  fixup.dat
  fixup_db.dat
  fixup_x.dat
  start4cd.elf
  start4db.elf
  start4.elf
  start4x.elf
  start_cd.elf
  start_db.elf
  start.elf
  start_x.elf

If you replace it with 4B, 400, or Pi5 all bets are off and you'd probably be better starting with a fresh installation onto a fresh SD card.
