PHP Errors When Upgrading Freeform & Tag From v3 to v4

Question

When trying to upgrade Solspace Freeform and Solspace Tag, I'm getting PHP errors.

For Freeform, I'm trying to update from 3.1.0 to 4.0.12. When I go to the Freeform module page, I get this PHP error:

A Database Error Occurred Error Number: 1146

Table 'db_production.exp_freeform_multipage_hashes' doesn't exist

TRUNCATE exp_freeform_multipage_hashes

Filename: third_party/freeform/upd.freeform.php

Line Number: 472

For Tag, I'm trying to update from 3.0.5 to 4.2.3, and I'm getting these errors when I try to access the module:

A PHP Error was encountered

Severity: Warning

Message: file_get_contents(/path/to/my/system/expressionengine/third_party/tag/tag.sql) [function.file-get-contents]: failed to open stream: No such file or directory

Filename: tag/upd.tag.php

Line Number: 817

A PHP Error was encountered

Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at /path/to/my/system/codeigniter/system/core/Exceptions.php:170)

Filename: core/Common.php

Line Number: 412

A Database Error Occurred The query you submitted is not valid.

Filename: third_party/tag/upd.tag.php

Line Number: 828

I've already tried completely re-uploading the files from scratch, making sure that the old files are gone from the system, but I still get these errors.

When updating freeform, you need to delete the old directories before uploading the new:

Updating:

Within your sites ./system/expressionengine/third_party/ directory, delete the freeform folder and upload the new one from the /system/expressionengine/third_party/ directory in your download package.
Within your sites ./themes/third_party/ directory, delete the freeform folder and upload the new one from the /themes/third_party/ directory in your download package.
Go to the Modules area in the ExpressionEngine control panel and click the Run Module Updates button.
Upgrading from Freeform 3.x (if applicable):
    Go to the Utilities tab in the Freeform control panel, and run the Migration utility.
    Review the Freeform 3.x to 4.x Upgrade Guide and update your templates as necessary.
