Linear Migration Deep Dive
Overview
Comprehensive guide for migrating from Jira, Asana, or GitHub Issues to Linear. Covers assessment, workflow mapping, data export, transformation, batch import with hierarchy support, and post-migration validation. Linear also has a built-in importer (Settings > Import) for Jira, Asana, GitHub, and CSV.
Prerequisites
Admin access to source system (Jira/Asana/GitHub)
Linear workspace with admin access
API keys for both source and Linear
Migration timeline and rollback plan

Step 2: Workflow Mapping
Jira -> Linear:
Jira Status Linear State (type) To Do Todo (unstarted) In Progress In Progress (started) In Review In Review (started) Blocked In Progress (started) + "Blocked" label Done Done (completed) Won't Do Canceled (canceled)
Jira Priority Linear Priority Highest/Blocker 1 (Urgent) High 2 (High) Medium 3 (Medium) Low/Lowest 4 (Low)
Jira Issue Type Linear Label Bug Bug Story Feature Task Task Epic (becomes Project or parent issue)
Asana -> Linear:
Asana Section Linear State
Backlog Backlog (backlog) To Do Todo (unstarted) In Progress In Progress (started) Review In Review (started) Done Done (completed)
Step 3: Export from Source System
interface JiraIssue {
key : string ;
summary : string ;
description : string ;
status : string ;
priority : string ;
issuetype : string ;
assignee ?: string ;
labels : string [];
storyPoints ?: number ;
parent ?: string ;
subtasks : string [];
}
async function exportJiraProject (
baseUrl : string ,
projectKey : string ,
authToken : string
): Promise <JiraIssue []> {
const issues : JiraIssue [] = [];
let startAt = 0 ;
const maxResults = 100 ;
while (true ) {
const jql = `project = ${projectKey} ORDER BY created ASC` ;
const response = await fetch (
`${baseUrl} /rest/api/3/search?jql=${encodeURIComponent (jql)} &startAt=${startAt} &maxResults=${maxResults} &fields=summary,description,status,priority,issuetype,assignee,labels,customfield_10016,parent,subtasks` ,
{ headers : { Authorization : `Basic ${authToken} ` , Accept : "application/json" } }
);
const data = await response.json ();
for (const issue of data.issues ) {
issues.push ({
key : issue.key ,
summary : issue.fields .summary ,
description : issue.fields .description ?.content
? convertAtlassianDocToMarkdown (issue.fields .description )
: issue.fields .description ?? "" ,
status : issue.fields .status .name ,
priority : issue.fields .priority ?.name ?? "Medium" ,
issuetype : issue.fields .issuetype .name ,
assignee : issue.fields .assignee ?.emailAddress ,
labels : issue.fields .labels ?? [],
storyPoints : issue.fields .customfield_10016 ,
parent : issue.fields .parent ?.key ,
subtasks : issue.fields .subtasks ?.map ((s : any s.key ) ?? [],
});
}
startAt += maxResults;
if (startAt >= data.total ) break ;
}
console .log (`Exported ${issues.length} issues from Jira ${projectKey} ` );
return issues;
}
Jira Markup -> Markdown Converter:
function convertJiraToMarkdown (text : string string {
if (!text) return "" ;
return text
.replace (/h([1-6])\.\s/g , (_, level ) => "#" .repeat (parseInt (level)) + " " )
.replace (/\*([^*]+)\*/g , "**$1**" )
.replace (/_([^_]+)_/g , "*$1*" )
.replace (/\{code(?::([^}]*))?\}([\s\S]*?)\{code\}/g , "```$1\n$2\n```" )
.replace (/\{noformat\}([\s\S]*?)\{noformat\}/g , "```\n$1\n```" )
.replace (/^\*\s/gm , "- " )
.replace (/^#\s/gm , "1. " )
.replace (/\[([^|]+)\|([^\]]+)\]/g , "$1" );
}
Step 4: Transform to Linear Format interface LinearImportIssue {
title : string ;
description : string ;
priority : number ;
stateId : string ;
assigneeId ?: string ;
labelIds : string [];
estimate ?: number ;
parentId ?: string ;
sourceId : string ;
}
async function transformJiraIssue (
jiraIssue : JiraIssue ,
stateMap : Map <string , string >,
userMap : Map <string , string >,
labelMap : Map <string , string >
): Promise <LinearImportIssue > {
const priorityMap : Record <string , number > = {
Highest : 1 , Blocker : 1 ,
High : 2 ,
Medium : 3 ,
Low : 4 , Lowest : 4 ,
};
const labelIds : string [] = [];
const typeLabel = labelMap.get (jiraIssue.issuetype );
if (typeLabel) labelIds.push (typeLabel);
for (const label of jiraIssue.labels ) {
const mapped = labelMap.get (label);
if (mapped) labelIds.push (mapped);
}
return {
title : jiraIssue.summary ,
description : convertJiraToMarkdown (jiraIssue.description ),
priority : priorityMap[jiraIssue.priority ] ?? 3 ,
stateId : stateMap.get (jiraIssue.status ) ?? stateMap.get ("Todo" )!,
assigneeId : jiraIssue.assignee ? userMap.get (jiraIssue.assignee ) : undefined ,
labelIds,
estimate : jiraIssue.storyPoints ?? undefined ,
sourceId : jiraIssue.key ,
};
}
Step 5: Import to Linear import { LinearClient } from "@linear/sdk" ;
async function importToLinear (
client : LinearClient ,
teamId : string ,
issues : JiraIssue [],
stateMap : Map <string , string >,
userMap : Map <string , string >,
labelMap : Map <string , string >
): Promise <{ created : number ; errors : number ; idMap : Map <string , string > }> {
const idMap = new Map <string , string >();
let created = 0 ;
let errors = 0 ;
const sorted = [...issues].sort ((a, b ) => {
if (a.subtasks .length > 0 && !a.parent ) return -1 ;
if (b.subtasks .length > 0 && !b.parent ) return 1 ;
return 0 ;
});
for (const jiraIssue of sorted) {
try {
const transformed = await transformJiraIssue (jiraIssue, stateMap, userMap, labelMap);
if (jiraIssue.parent && idMap.has (jiraIssue.parent )) {
transformed.parentId = idMap.get (jiraIssue.parent );
}
const result = await client.createIssue ({
teamId,
title : transformed.title ,
description : `${transformed.description} \n\n---\n*Migrated from ${jiraIssue.key} *` ,
priority : transformed.priority ,
stateId : transformed.stateId ,
assigneeId : transformed.assigneeId ,
labelIds : transformed.labelIds ,
estimate : transformed.estimate ,
parentId : transformed.parentId ,
});
if (result.success ) {
const issue = await result.issue ;
idMap.set (jiraIssue.key , issue!.id );
created++;
if (created % 25 === 0 ) console .log (`Imported ${created} /${sorted.length} ` );
}
await new Promise (r =>setTimeout (r, 100 ));
} catch (error : any ) {
console .error (`Failed to import ${jiraIssue.key} : ${error.message} ` );
errors++;
}
}
console .log (`Import complete: ${created} created, ${errors} errors` );
return { created, errors, idMap };
}
Step 6: Post-Migration Validation async function validateMigration (
client : LinearClient ,
teamId : string ,
sourceIssues : JiraIssue [],
idMap : Map <string , string >
): Promise <{ valid : boolean ; issues : string [] }> {
const problems : string [] = [];
if (idMap.size < sourceIssues.length ) {
problems.push (`Missing: ${sourceIssues.length - idMap.size} issues not imported` );
}
const sample = sourceIssues.slice (0 , 50 );
for (const source of sample) {
const linearId = idMap.get (source.key );
if (!linearId) {
problems.push (`${source.key} : not imported` );
continue ;
}
try {
const issue = await client.issue (linearId);
if (issue.title !== source.summary ) {
problems.push (`${source.key} : title mismatch` );
}
} catch {
problems.push (`${source.key} : not found in Linear (${linearId} )` );
}
await new Promise (r =>setTimeout (r, 50 ));
}
return { valid : problems.length === 0 , issues : problems };
}
Post-Migration Checklist [ ] All issues imported and validated
[ ] Parent/child relationships correct
[ ] Labels and priorities mapped correctly
[ ] User assignments transferred
[ ] Integrations reconfigured (GitHub, Slack)
[ ] Team workflows customized in Linear
[ ] Team trained on Linear
[ ] Source system set to read-only
[ ] Parallel run period started (2 weeks recommended)
[ ] Archive source system after parallel run
Error Handling Issue Cause Solution User not found Unmapped email Add to userMap Rate limited Too fast import Increase delay to 200ms State not found Unmapped status Update stateMap Parent not found Import order wrong Sort parents before children Markup broken Incomplete conversion Improve markdown converter
