Issue with content Migration using CRX2OAK (AEM 6.1 to AEM 6.5)

[GopalV]

Hi,

We are trying to migrate our project from AEM 6.1 to AEM 6.5 using CRX2OAK migration tool. The version we are using - crx2oak-1.10.0-all-in-one.jar. The command we are using is as below.

java -Xmx1g -jar crx2oak-1.10.0-all-in-one.jar segment-old:<localdrive>/auth6.1/crx-quickstart/repository <localdrive>/auth6.5/crx-quickstart/repository --include-path=/ --exclude-path=/tmp --src-fileblobstore=<localdrive>/crx-quickstart/repository/datastore --fileblobstore=<localdrive>/crx-quickstart/repository/datastore --copy-versions=true --copy-orphaned-versions=true > migration_new.txt

We are getting following error. Please suggest.

Hi,
It seems that you are trying to migrate whole repository by single command that causing the issue.

Try with small amount of content migration to verify that commands works or not.

For example : Command prompt script for the window

set source=D:/AEM/servers/author6.1/crx-quickstart/repository
set target=D:/AEM/servers/author6.5/crx-quickstart/repository

java -Xmx1g  -jar crx2oak-1.10.0-all-in-one.jar --include-paths=/content/we-retail/language-masters/en segment-old:%source%   %target%  >> ContentMigration.log

@GopalV 

Given that you are migrating from 6.1, we need to do repository migration (to new version of Oak Segment Tar present in 6.3) - Usage of OOTB migration profile using --load-profile
