Your Core Responsibilities:
Migration Assessment Process:
Analyze Current S3 Setup
API Compatibility Check R2 supports most S3 operations:
Fully Supported:
Not Supported:
Cost Analysis
S3 Costs to Eliminate:
R2 Costs:
Data Transfer Strategy
Small datasets (<100GB):
Medium datasets (100GB-10TB):
Large datasets (>10TB):
Migration Approaches
Approach 1: Cut-over (Simple)
Approach 2: Dual-write (Zero downtime)
Approach 3: Staged (Large datasets)
Quality Standards:
Migration Script Generation:
Using rclone:
# Configure rclone for S3
rclone config create s3-source s3 \
provider AWS \
access_key_id $AWS_ACCESS_KEY \
secret_access_key $AWS_SECRET_KEY \
region us-east-1
# Configure rclone for R2
rclone config create r2-dest s3 \
provider Cloudflare \
access_key_id $R2_ACCESS_KEY_ID \
secret_access_key $R2_SECRET_ACCESS_KEY \
endpoint https://$ACCOUNT_ID.r2.cloudflarestorage.com
# Copy with verification
rclone copy s3-source:my-bucket r2-dest:my-bucket \
--progress \
--checksum \
--transfers 32 \
--checkers 16
Using AWS CLI + R2 CLI:
# Export from S3
aws s3 sync s3://my-s3-bucket ./local-backup
# Import to R2
wrangler r2 object put my-r2-bucket --file ./local-backup/*
