Fastest way to migrate to a bigger SSD (18.04)

Question

I've seen a few postings about migration with older Ubuntu versions.

What's the fastest way to migrate 120GB (80GB full) to a 1TB SSD under Ubuntu 18.04?

• live duplicate or via image possible
• how to extend the new volume on the new SSD?

Because I've only a limited time window once I've started I'd be happy for suggestions for the fastest way to get new system up and running again.

Answer 1

What about using a Live System and

sudo dd if=/dev/sdx0 of=/dev/sdy0

and

sudo resize2fs /dev/sdy0

afterwards to resize the partition.

With sdx0 being your old partition and sdy0 being the new one.

For a fast migration you have more than a couple of choice (and for fast not use dd, it copy bit per bit)

common used tools:

• https://www.acronis.com/en-us/ (should free to personal use)
• https://clonezilla.org/ (open source)
• https://www.symantec.com/products/ghost-solutions-suite (commercial)

You can also decide to create a tar of your OS and restore it (more manual work to do but still fast then dd)

• https://help.ubuntu.com/community/BackupYourSystem/TAR

Personally I suggest you to use clonezilla, have a large community and a good Knowledge on the common issues can be encountered and of course because is opensource!
