Migrating from 2.6.x to 3.4.x

calendar_today June 16, 2026 person perumalkuk domain meteor

Have production meteor app in 2.6.x with android app (several apps pointing to the same app - changes layout based on customer). The app is used by some 5000 users. After several tries was able to use Claude to migrate to 3.x ( had huge problem with packages and global variables) and to 3.4.1 surprisingly with no problem ( though others have reported it).
