Imports and Existing Content

[ri_gamer]

So, I am rebuilding my main realm, since I've still had no response from LWD on my issues submitted, and looking for suggestions on best way to export/re-import data.

My realm uses 5E Ruleset, content market imports include:
5E SRD
Tomb of Beasts
Rise of the Runelords (PF)

I exported from a backup of my previous realm:
All SRD modifications and additions I made (i.e) missing spells, names, etc
Modifications to the Runelords adventure to convert it to 5E

Any suggestions on the best order to re-import these to preserve my changes? With the rules, I found I had to import the SRD first or got a "Attempt to commit a transaction after a rollback occurred" error. (Error submitted, but expect no response)

Thanks for the support from the community.
