Import pics from E drive to E drive on new PC

[Gingersnaps22]

I have Lightroom6 on my desktop  PC (Win7), with program and catalog on the C-drive (SSD).  All my picture files are in a folder on a separate 4TB internal E-drive (magnetic).  I have the latest backup copy of the catalog that is made when Lightroom6 shuts down - stored in another folder on that E-drive.

I have recently bought a new Win10 desktop and purchased Lightroom Classic for it, installing it on the C-drive.  I plan to physically move the 4TB picture drive from the old PC to the new PC, also assigning it as the E-drive on the new machine.

What is the best/easiest way to get the latest catalog on the 4TB E-drive imported into the Lightroom Classic program on the new Win10 PC?  Once I do this, will the new Lightroom Classic know that all the picture files are on the E-drive as my original Lightroom6 did?

First- Do NOT IMPORT ANYTHING!.

I refer you to this article- Move Lightroom to a new computer? | The Lightroom Queen 

With these comments-

Step#1 'Preparation':  You have this done- Your photo files are on the transferred E:drive

Step#2 'Backups':  You have one Catalog backup on the E:drive,  but do you also have other catalog backups (AND Photos) on another physical drive? (Not the E:drive?)

Step#5 'Open the Catalog':  A fresh install of Lr-Classic in the 'new' PC may open a new empty Catalog. If this happens- Exit this empty catalog immediately, then with File Explorer locate your copied Lr6 Catalog (on C:drive) and [Double-Click] to 'open' it.   You will be asked to upgrade the Catalog for v10: Accept!

Step#6 'Relink missing files' should not be needed if the Catalog recognizes the E:drive as in the 'old' PC.

Steps# 7 & 8:  Are Important, as you may have many Presets and Plugins that you would need to also copy across to the 'new' system. (Save a backup of these files also!)

Presets to a New Computer

When Lr-Classic is installed and with your Catalog upgraded, there will be some differences with Lightroom file locations, this article  details -

Then, "will the new Lightroom Classic know that all the picture files are on the E-drive as my original Lightroom6 did?"  YES!
