Lost some data and content after upgrading from Craft 4 to Craft 5

[bhashkar007]

Bug Description

I had built a website using Craft 2.6.3019 several years ago and Neo field is widely used with the combination of Matrix field. Now we are planning to upgrade it to Craft 5 (latest version). So I did:

• Upgrade from Craft 2 to Craft 3 (successful - everything is fine.)
• Upgrade from Craft 3 to Craft 4 (successful - everything is fine).
• Upgrade from Craft 4 to Craft 5 (latest version Craft 5.4.2, Neo 5.2.5) - Upgrade and migration went successful but while checking entries Craft 5 website, I found that data/content of some fields were lost.

Please help for it.

Steps to reproduce

• Upgrade Craft 4 to Craft 5 using Neo

Expected behaviour

No response

Neo version

5.2.5

Craft CMS version

5.4.2

What is the affected Neo field's propagation method?

No response

Does this issue involve templating, and if so, is eager-loading used?

This is not a templating issue

This is happening to me too, just in an upgrade from 4 to 5. And it was working before, so I think a new neo upgrade may have done it.

I pinned my neo to 5.2.2 and re-upgraded and it seems to have fixed the problem at least so I can go forward with my upgrade

@LinneaHarts It didn't work for me. I re-upgraed from Craft 4 to Craft 5 with Neo v5.2.2 and still having same problem.

Are there any particular field types that are losing content?

EDIT: sorry, complete different issue

[bhashkar007]

Thank you, @ttempleton I found this issue in entries of different sections basically with the field types like:

• Plain Text
• Plain Text (multiline)
• CKEditor (which is migrated from Redactor)
  I am afraid that there may be other field types also. It's something large website with 4k+ entries and 14 languages (sites). Please share your thoughts,

[ttempleton]

If possible, could you please send both your Craft 4 and 5 composer.json/lock files, and your Craft 4 database backup (so I can see the expected content on Craft 4 and then attempt the upgrade to see where the content is being lost) to [email protected], and we'll have a look.

@bhashkar007 I have also faced the same issue, It gets fixed when you just re-save the field again from Settings->Fields.

Confirming that I also had the same issue, specifically with CKE fields, and it was resolved by following @navneetshukla9's suggestion of re-saving each Neo field in Settings->Fields.

My above request remains open for anyone experiencing this.
